IS MY MOD LEGAL?

Most Permissive States for Lift Kits (2026)

Thirty-six states put some limit on how high you can lift a vehicle — usually a bumper or frame height cap that scales with weight, occasionally a variance measured against your own truck's factory height.

Fourteen states set no lift-height rule at all. No bumper cap, no frame ceiling, no variance limit. General equipment law still applies — headlights have to sit at legal height, bumpers have to be present where required, lights and mirrors have to work — but the lift itself is not regulated.

Those fourteen are Alabama, Colorado, Iowa, Kansas, Kentucky, Louisiana, Montana, Nebraska, New Mexico, Oklahoma, Oregon, South Dakota, Texas, and Wyoming. Here are the ten best of them for a lifted build, re-verified against statute and administrative code in August 2026.

1. Texas - No Limit, No Inspection

Lift Kits in Texas

Texas sets no lift-height, frame-height, or bumper-height limit for passenger vehicles, and since safety inspections for non-commercial vehicles ended in January 2025 there is no annual checkpoint either. Combined with no wheel-protrusion rule, it is one of the strongest overall packages in the country for a lifted truck.

2. Montana - Big Sky, No Ceiling

Lift Kits in Montana

Montana imposes no lift or bumper-height cap. It does require fenders, splash aprons, or flaps on rearmost wheels — a spray-control rule, not a height one.

3. Colorado - Elevation Without a Limit

Lift Kits in Colorado

Colorado has no statutory lift-height or bumper-height restriction for passenger vehicles. Worth pairing with a note that Colorado does regulate lowering, so a build that goes both directions needs checking.

4. Wyoming - Empty Rulebook

Lift Kits in Wyoming

Wyoming sets no lift, frame, or bumper height limits, and no wheel-protrusion rule either. Consistently hands-off across nearly every category we track.

5. Oklahoma - No Height Cap

Lift Kits in Oklahoma

Oklahoma sets no lift-height limit. It does require a rubber or fabric apron behind the rearmost wheels where fenders are absent, sized against a 22.5-degree spray angle — again, spray control rather than height.

6. South Dakota - Hidden Paradise

Lift Kits in South Dakota

South Dakota has no lift-height restriction and no lowering restriction, which makes it unusually flexible for builders working in both directions.

7. Kansas - Nothing on the Books

Lift Kits in Kansas

Kansas sets no suspension, frame-height, or bumper-height statute for passenger vehicles.

8. Nebraska - Plains-State Freedom

Lift Kits in Nebraska

Nebraska imposes no lift-height cap. Its equipment code requires fenders, covers, flaps, or splash aprons that minimize rear spray, with no height component.

9. Iowa - Repealed and Left Alone

Lift Kits in Iowa

Iowa sets no lift-height limit for passenger vehicles. General height, weight, and width requirements apply the same way they do to any other vehicle.

10. New Mexico - Lenient Across the Board

Lift Kits in New Mexico

New Mexico sets no lift-height or bumper-height limit. Fender and mud-flap rules are enforced, so keep spray control in mind on a tall build with wide tires.

The Ones People Get Wrong

Three states show up on "most permissive" lists constantly and belong nowhere near one:

  • Massachusetts allows just 2 inches of change from the manufacturer's height — the tightest limit in the country.
  • New Jersey requires an elevated-vehicle approval certificate for any elevation above original height.
  • New Hampshire confines passenger bumpers to a 16-to-20-inch band, and going beyond it requires prior approval from the DMV director.

Alaska, Delaware, Hawaii, Idaho, and Maine also appear on those lists but all set real bumper or frame caps.

Permissive Is Not Unregulated

Even in the fourteen no-limit states, a few rules still reach a lifted truck. Headlight height ranges apply everywhere. Several states require mudguards specifically because the vehicle has been altered from original frame height — Utah's rule works exactly that way. And a lift that raises your bumper past an oncoming driver's hood line can still draw an equipment citation under a general safety provision even where no number exists.
