ALABAMA
There aren't codes dealing specifically with the suspension
components; rather, you'll have to base your mods on the reflectors.
They can't be more than 60 inches above the ground.
--------------------------------------------------------------------------------
ALASKA
Alaska is another state that bases it's laws on the lights, and in
this case it's the distance from the headlights and taillights to
the ground, which is 54 inches max and 24 minimum front and rear.
One note: This state requires mudflaps.
--------------------------------------------------------------------------------
ARIZONA
It's all about mudflaps. The rear fender's spashguards can't
be more than 8 inches from the ground and must be wide enough, of
course, to actually cover the full tread of the tires.
However, 3/4-ton or lighter pickups are exempt, unless you've
increased the OE bumper height. So, in other words, lift it,
and you're stuck following the mudflap rules. Leave your pickup stock, and you can skip the flaps. Also keep in mind that empty or loaded, your truck can't be taller than 13 feet 6 inches.
--------------------------------------------------------------------------------
ARKANSAS
There's no law governing suspension upgrades, but there is a statute
that restricts the height of headlights. They can't be lower than 24
inches or higher than 54 inches from the ground. However,
overall height restriction is 13 feet 6 inches without permit,
thereby limiting all those dreams you just had.
--------------------------------------------------------------------------------
CALIFORNIA
What you can do is dependent on the GVWR. If your truck's is
4,500 pounds, the maximum frame height is 27 inches. If the
GVWR is 4,501 to 7,500 pounds, it's 30 inches, and for 7,501- to
10,000 pounders, it's 31 inches. Also keep in mind that the lowest portion of the body floor can't be more than 5 inches above the top of the frame.
--------------------------------------------------------------------------------
COLORADO
No altering from the OE design is allowed. Psych! It's not allowed unless you follow the rules: Headlights can't be more than 44 inches high, while taillights reach their limit at 72 inches.
--------------------------------------------------------------------------------
CONNECTICUT
Modifying the factory bumper height is OK, as long as you keep it at
30 inches from the ground, or lift the vehicle no more than 4
inches.
--------------------------------------------------------------------------------
DELAWARE
Short and sweet, without legal-eagle mumbo-jumbo: Don't let more
than 30 inches get between the ground and the bottom of the bumper.
--------------------------------------------------------------------------------
DISTRICT OF COLUMBIA
The headlamps on every motor vehicle (and that means your motorcycle
too if you've got on) must stay below 54 inches, and each taillamp
must not be higher than 72 inches. The low for the front is
24, and for the rear 15 - but we would hope you'd be altering your
truck in the other direction.
--------------------------------------------------------------------------------
FLORIDA
If your truck's net weight is less than 2,000 pounds, the max bumper height is 24 inches front and 26 inches rear. If it's more than 2,000 but less than 3,000, it's 27 front and 29 rear. And if it hits the scales between 3,000 and 5,000 pounds, it's 28 and 30 inches
--------------------------------------------------------------------------------
GEORGIA
If you modify the OE bumper more than 2 inches above (or below, for
that matter) the manufacturer's spec, don't be surprised if you're
cited.
--------------------------------------------------------------------------------
HAWAII
Hawaii also determines what's OK based on the GVWR. If your
truck is 4,500 pounds or less, the from and rear bumpers' maximum
height is 29 inches. If you're looking at 4,501 to 7,500
pounds, it's 33 inches for both. And 7,501 to 10,000 pounds?
Don't make them higher than 35 inches at either end. Also be
aware that the allowable distance between the body and the framerail
tops off at 3 inches.
--------------------------------------------------------------------------------
IDAHO
Lift laws here depend on GVWR - 4,500 pounds or less, the front
bumper cab be up to 24 inches and the rear 26 inches. For
4,501 to 7,500 pounds, it's 27 inches in front and 29 out back, and
for 7,501 to 10,000 pounds, it's 28 and 30 inches.
Interestingly enough, 4x4's and dual-wheel trucks with 10,000-pound
or lighter GVWR can have 30-inch-tall bumpers up front and 31 in
back.
--------------------------------------------------------------------------------
ILLINOIS
You can't lift the body from the chassis more than 3 inches.
In terms of bumper height, a 4,500 pound GVWR or less and your front
bumper can't go higher than 24 inches, and the rear must be no more
than 26 inches. GVWRs between 4,501 and 7,500 mean 27 inches
at the front and 29 at the rear. Finally. if your truck is
between 7,501 and 9,000, the allowable altering is 28 and 30 inches.
--------------------------------------------------------------------------------
INDIANA
Simply put, that bumper needs to stay within 3 inches of the factory
height. Keep those headlights at 54 inches while your at it.
--------------------------------------------------------------------------------
IOWA
We've been told that Iowa has repealed requirements concerning
lifted 4x4s. For now, that means that general height, weight,
and width requirements that apply to all other vehicles in the state
apply to your four-by. Translation: The height cannot exceed 13 feet
6 inches, and the width can't go beyond 8 feet.
--------------------------------------------------------------------------------
KANSAS
There aren't laws specifically about the suspension, but rather
about headlight, taillamp, and reflectors. Headlights should be no
higher than 54 inches (no lower than 24 inches), and the taillamps
can't reach higher than than 72 inches (or below 15).
Reflectors must be present front and rear (out back they can be
incorporated into the light or stand alone) and can't be higher than
60 inches or lower than 15.
--------------------------------------------------------------------------------
KENTUCKY
Currently, there are no restrictions on terms of bumper height.
The Kentucky General Assembly has addressed the issue before but, lo
and behold, no one could agree on anything. Just keep it at
what most mortals would call safe.
--------------------------------------------------------------------------------
LOUISIANA
It's a headlight state. No matter what kind of motor vehicle
you drive, the lights can't be higher than 54 inches. Alter the
suspension however you deem fit, as long as the lights are up to
code. FYI, foglights can't be higher than 30 inches from the ground.
--------------------------------------------------------------------------------
MAINE
Headlights: Don't even think about going higher than 54
inches. However, keep in mind that the original suspension
cannot be "disconnected," but don't let that stop you from
bolting on heavy-duty shocks and overload springs. Other
need-to-knows: Don't remove or disconnect the ABS, and the
tires can only be two sizes larger than the manufacturer's
recommendation. Spring-shackle extensioins are also a no-no. More info
--------------------------------------------------------------------------------
MARYLAND
No trucks or multipurpose vehicles with a GVWR of 10,000 pounds or
less can be taller than 28 inches. A truck beyond 10,000
pounds - but not more that 18,000 pounds - can go beyond 30 inches
(you Excursions owners just made it into that first grouping under
the wire). Lift more than those 30, and you'll be ticketed
and/or given a Safety Equipment Repair Order (SERO) to fix the violation.
--------------------------------------------------------------------------------
MASSACHUSETTS
Get your calculator: The maximum allowable mechanical lift (as
well as what's acceptable in terms of bigger rubber) can be
determined by this formula:
Maximum Lift = Wheelbase x Wheel Track divided by 2200
For example, if you did the formula and came up with 2 inches, then a 2 inch lift and a 2 inch increase in tire size is allowable, equaling a total lift of 4 inches over stock.
--------------------------------------------------------------------------------
MICHIGAN
Lift blocks between the front axle and springs, or lift blocks that
exceed 4 inches in height between the rear axle and springs, are not
allowed. Shackle replacements cannot exceed OE length by more
than 2 inches, and ixnay on the coil spring spacers. In terms
of acceptable height, less than 4,501 GVWR, and your frame height
cannot exceed 24 inches, and the bumper height can't go beyond 26
inches. For GVWR's between 4,501 and 7,500, those numbers are
24 and 28 inches. For 7,501 and 10,000-pound vehicles, keep
the height at 26 and 30 inches.
--------------------------------------------------------------------------------
MINNESOTA
The maximum legal height for bumpers is 25 inches from the bottom of
the bumper to the ground. If you attach something to the
bumper to make it conform to the legal height, it must be just as
strong as the factory bumper or meet SAE standards. Simply
bolting on pieces of wood or metal isn't gonna cut it folks.
If you slap on a lift kit, you might actually be required to
register your truck as a "reconstructed" vehicle, and that
would mean you'll have to pay additional road-use tax and need an
inspection where a new VIN would be applied.
--------------------------------------------------------------------------------
MISSISSIPPI
No vehicle can be modified in any way that will put it over the
state's 8-inch total-lift limit, and the maximum suspension lift
front and rear is 6 inches (so make sure your big tires won't be
over the limit if you raise the suspension that much).
--------------------------------------------------------------------------------
MISSOURI
Here's another state that use GVWR as the bumper-height guideline.
For vehicles 4,500 pouinds and under, the front bumper can't be taller than 24 inches and the rear must see no more than 26 inches. For 4,501 to 7,500 pounds, it's 27 inches in front and 29 rear, and for 7,501 to 9,000 pounds, it's 28 and 30 inches.
--------------------------------------------------------------------------------
MONTANA
No laws here, but your truck will need the lighting requirement,
which is that the headlights are no higher than 72 inches or lower
than 15 inches.
--------------------------------------------------------------------------------
NEBRASKA
There aren't any specific laws concerning lift kits, but mudflaps get all the attention. They must block the entire width of the tires.
--------------------------------------------------------------------------------
NEVADA
We'll cut to the chase. The
bumper height, be it front or rear, cannot go beyond 24 inches.
--------------------------------------------------------------------------------
NEW HAMPSHIRE
No vehicle's height (and we're talking loaded too), may be taller than 13 feet 6 inches. Don't change the height or alter the bumper in any way that would make it farther than 20 inches from the ground.
--------------------------------------------------------------------------------
NEW JERSEY
You can raise the suspension only 4 inches above stock height.
Go any higher and your truck becomes classified as a "High
Rise" and it must undergo a stability test at a state facility.
--------------------------------------------------------------------------------
NEW MEXICO
The restrictions this state has are that headlamps can't be higher
than 54 inches, and taillamps can't be higher than 72 inches.
However, it's no-holds-barred on the type of lift used.
--------------------------------------------------------------------------------
NEW YORK
All '90 and newer commercial vehicles and trucks can't go crazy and
get that bumper above 24 inches from the ground. Also keep in
mind tht headlights must not be more than 54 inches above the cement, and taillights can't be higher than 72 inches. Turn-signal lights can't exceed 83 inches.
--------------------------------------------------------------------------------
NORTH
CAROLINA
Don't even think about going higher than 6 inches from the factory
height - unless, of course, you get a written OK from the
Commissioner of Motor Vehicles. You don't need a permission
slip if yours is a multipurpose ride atop a truck chassis that sees
some dirt.
--------------------------------------------------------------------------------
NORTH DAKOTA
A height of 14 feet, loaded or unloaded, is the limit. Keep in
mind that if your tires poke out from the body, you're best advised
to stick on fender flares to keep the police at bay.
--------------------------------------------------------------------------------
OHIO
This state keeps an eye on the GVWR for bumper height. For 4,500 pounds and under, 24 inches is the max at front, 26 at the rear, and 4,501 to 7,500 is 27 to 29. For 7,501 to 10,000, it's 28 and 31 inches. If the body or truck-bed height is altered, the difference in height between the body floor and/or the bed floor to the top of the framerail can be no more than 4 inches.
--------------------------------------------------------------------------------
OKLAHOMA
Before you pick out that lift kit, keep in mind that headlights can
be no more than 54 inches from the ground, and the taillights can't
exceed 72 inches.
--------------------------------------------------------------------------------
OREGON
Oregon doesn't have a maximum bumper-height law, but headlights can be only 54 inches from the center of the headlight to the asphalt. Also, maximum height of a vehicle, with anything on top or loaded is 14 feet.
--------------------------------------------------------------------------------
PENNSYLVANIA
Be aware that increasing the wheel track by using spacers or similar doodads thicker than 1/4 inch is a very bad move. On medium and heavy duty trucks, the rear bumper must be within 30 inches of the ground when the truck is unloaded.
--------------------------------------------------------------------------------
RHODE ISLAND
For all vehicles with a 10,000-pound GVWR or less, you can raise the
chassis or body no more than 4 inches from the OE height.
--------------------------------------------------------------------------------
SOUTH CAROLINA
You can't modify either up or down by more than 6 inches from the
original height.
--------------------------------------------------------------------------------
SOUTH DAKOTA
There aren't regulations for suspensions, per se, but the taillights
can be no higher than 72 inches.
--------------------------------------------------------------------------------
TENNESSEE
There can be no more than 4 inches between the body floor and the
top of the frame. The distance between the bumper and the
ground is 24 inches for GVWRs of 4,500 and less; 26 inches for 4,501
tto 7,500; and 28 inches for 7,501 to 10,000.
--------------------------------------------------------------------------------
TEXAS
Laws concern lighting but not bumper height or even lift blocks.
The headlamps must be mounted between 24 and 54 inches from the
ground, the taillamps between 15 and 72, and foglamps between 12 and
30.
--------------------------------------------------------------------------------
UTAH
After being told it's a "mathmatical nightmare" to figure
out by one local trooper, we got the scoop from another trooper: If
your vehicle's wheelbase is 100 inches or less, the most you can
lift can be determined by:
Maximum Lift = Wheelbase x Wheel Track divided by 2200
For 4x4 wheelbases beyond 100 inches, you can lift a total of 8
inches, but you'll have to remember your new tires do that equation
(so if you lift 4 inches, you can go up in tire size that much too).
--------------------------------------------------------------------------------
VERMONT
For trucks and multipurpose vehicles, the allowable bumper-height
increase for front bumpers and rear bumpers depends on the GVWR.
For 4,500 pounds and under, it's 24 inches front and 26 inches rear.
For 4,501 to 7,500, it's 27 and 29, and for 7,501 to 10,000, it's 28
and 31.
--------------------------------------------------------------------------------
VIRGINIA
Don't even think about driving on these highways if there is more
than 28 inches between the bumpers and the road if your truck falls
in the 4,500-pound GVWR rating. For 4,501 to 7,500 pounds, the
front bumper must stay lower than 29 inches and the rear 30 inches;
for 7,501 amd 15,000 pounds, it's 30 at the front and 31 at the rear.
--------------------------------------------------------------------------------
WASHINGTON
You can lift your truck in Washington without fear, as long as the
kit is manufactured by an aftermarket company and is designed for
your make and model of truck, as well as installed the right way.
You know this already, right? Body lifts can't use more than a 3
inch spacer and are not allowed to rise the body more than 4 inches
above the frame after all components are installed.
--------------------------------------------------------------------------------
WEST VIRGINIA
The most space you can have between the body and frame are 3 inches,
while the acceptable gap between the bumpers and the ground is 31
inches for a 10,000-pound or less GVWR or less. More weight
than that, you're free and clear.
--------------------------------------------------------------------------------
WISCONSIN
Wisconsin law says that vehicles with an 8,000 pound GVWR can be
pushed 5 inches above the OE height, and the tires can be increased
by up to 4 inches in radius over the factory size, equaling an
acceptable 9-inch lift.
--------------------------------------------------------------------------------
WYOMING
There are no official statutory gidelines for bumper height, frame
height, rear blocks, or shakle lifts - all laws refering to these
alterations say the vehicle must simply be in "safe"
working condition.
