Lift Laws
From Faq
- There are no laws dealing specifically with the suspension components. Modifications to the truck will be based on reflector placement which cannot be more than 60 inches above the ground.
- The maximum distance from the headlights and taillights to the ground is 54 inches and 24 inches minimum front and rear. Mudflaps are also required.
- The rear mudflaps cannot be more than 8 inches from the ground and must be wide enough to actually cover the full tread of the tires. 3/4-ton or lighter pickups are exempt, unless the OEM bumper height has been increased. Empty or loaded, a truck cannot be taller than 13 feet 6 inches.
- There's no law governing suspension upgrades, but there is a statute that restricts the height of headlights which can't be lower than 24 inches or higher than 54 inches from the ground. Overall height restriction is 13 feet 6 inches without permit.
- Frame height can be no more than 27" for vehicles with a GVWR under 4500 pounds. For heavier vehicles the limit is 30". Body lifts cannot exceed 5". Vehicle headlight height shall not surpass 42" to the center of the headlight.
- Headlights cannot be more than 44 inches high, while taillights reach their limit at 72 inches.
- 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.
- No more than 30 inches can be between the ground and the bottom of the bumper.
- Headlights must stay below 54 inches, and taillights must not be higher than 72 inches.
- If 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 inches front and 29 inches rear. If between 3,000 and 5,000 pounds, it's 28 inches front and 30 inches rear.
- OEM bumper height cannot be modified more than 2 inches above or below the manufacturer's spec.
- If truck is 4,500 pounds or less, the front and rear bumpers' maximum height is 29 inches. Between 4,501 to 7,500 pounds, it's 33 inches for both. And 7,501 to 10,000 pounds no more than 35 inches at either end. Also be aware that the allowable distance between the body and the framerail tops off at 3 inches.
- Lift laws here depend on GVWR - 4,500 pounds or less, the front bumper can 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 inches rear, and for 7,501 to 10,000 pounds, it's 28 inches front and 30 inches rear. 4x4's and dual-wheel trucks with 10,000-pound or lighter GVWR can have 30 inch tall bumpers up front and 31 inches in the rear.
- The body cannot be lifted from the chassis more than 3 inches. In terms of bumper height, a 4,500 pound GVWR or less and 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 inches in the rear. If between 7,501 and 9,000, the allowable altering is 28 inches front and 30 inches rear.
- Bumper needs to stay within 3 inches of the factory height and headlights no more than 54 inches.
- General height, weight, and width requirements that apply to all other vehicles in the state apply to 4x4's. The height cannot exceed 13 feet 6 inches, and the width cannot go beyond 8 feet.
- There are no laws specifically about the suspension, but rather about headlights, taillights, and reflectors. Headlights should be no higher than 54 inches and no lower than 24 inches, and the taillights should not be higher than than 72 inches or below 15 inches. Reflectors must be present front and rear and cannot be higher than 60 inches or lower than 15 inches.
- Currently, there are no restrictions on terms of bumper height.
- Headlights cannot be higher than 54 inches. Foglights cannot be higher than 30 inches from the ground.
- Headlights cannot be higher than 54 inches. The original suspension cannot be "disconnected". Other items of importancen: Do not remove or disconnect ABS, and the tires can only be two sizes larger than the manufacturer's recommendation. No spring-shackles are allowed.
- No trucks or multipurpose vehicles with a GVWR of 10,000 pounds or less can be taller than 28 inches. More than 10,000 pounds but not more that 18,000 pounds cannot go beyond 30 inches.
- The maximum allowable mechanical lift 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.
- 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 OEM length by more than 2 inches. In terms of acceptable height, less than 4,501 GVWR, and your frame height cannot exceed 24 inches, and the bumper height cannot 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.
- 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 standard. An addition of a "lift kit" may actually require you 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.
- 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.
- For vehicles 4,500 pouinds and under, the front bumper cannot be taller than 24 inches and the rear must not be more than 26 inches. For 4,501 to 7,500 pounds, it's 27 inches in front and 29 inches rear, and for 7,501 to 9,000 pounds, it's 28 inches front and 30 inches rear.

- All '90 and newer commercial vehicles and trucks bumpers must not have no more than 24 inches between it and the ground. Headlights must not be more than 54 inches above the ground and taillights cannot be higher than 72 inches. Turn-signal lights cannot exceed 83 inches.
- No more than 6 inches from the OEM height of the vehicle.

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.
- Headlights can be no more than 54 inches from the ground and taillights cannot exceed 72 inches.
- Headlights can be only 54 inches from the center of the headlight to the ground. Maximum height of a vehicle with anything on top or loaded is 14 feet.
- Increasing the wheel track by the use of spacers thicker than 1/4 inch is illegal. On medium and heavy duty trucks, the rear bumper must be within 30 inches of the ground when the truck is unloaded.

- No more than 6 inches from the OEM height.
- Taillights can be no higher than 72 inches.
- 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 to 7,500; and 28 inches for 7,501 to 10,000.
- Laws concern lighting but not bumper height or even lift blocks. The headlights must be mounted between 24 and 54 inches from the ground, the taillights between 15 and 72 inches from the ground, and foglamps between 12 and 30 inches from the ground.
- If 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 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 inches front and 29 inches rear, and for 7,501 to 10,000, it's 28 inches front and 31 inches rear.
- No more than 28 inches between the bumper and the ground 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 and 15,000 pounds, it's 30 inches front and 31 inches rear.
- As long as the kit is manufactured by an aftermarket company and is designed for your make and model of truck it is legal to lift your vehicle. Body lifts cannot use more than a 3 inch spacer and are not allowed to raise the body more than 4 inches above the frame after all components are installed.
- Space between the body and frame cannot be more than 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.
- Vehicles with an 8,000 pound GVWR can be pushed 5 inches above the OEM height and the tires can be increased by up to 4 inches in radius over the OEM size.
- There are no official statutory guidelines for bumper height, frame height, rear blocks, or shakle lifts - all laws relating to these alterations say the vehicle must simply be in "safe" working condition.
