Lift Kit Laws by State: Rules and Guidelines for Lift Enthusiasts

There’s nothing quite like hitting the open road in a lifted truck, but not if you’re worried about getting stopped by the cops. Every state has its own lifted truck laws, and no two states are exactly alike. Even if you plan on spending most of your time off-road, you need to comply with your state’s rules and guidelines for lifted trucks.

You may scoff at the idea of anyone telling you what you can and can’t do with your truck, but these laws put an emphasis on safety. They’re designed to keep you and the other drivers on the road out of harm’s way. Some regulations limit the height of lifted trucks, while others mandate specific safety requirements. It all depends on where you live.

As the owner of a lifted truck, it’s your responsibility to stay up to date with your area’s lifted truck laws. These laws are subject to change, so take a moment to contact your local branch of government for the latest information before you invest in truck lift kits. If you’re traveling across state lines, research your destination and all the states you plan on hitting along the way. Here’s our state-by-state breakdown of all the laws you need to know.

NOTE:

When referring to the frame height, most states measure from the center of your tail lights or headlights down to the pavement. Keep a tape measure handy to make sure your vehicle complies with the law.

Alabama

Alabama is fairly lax when it comes to suspension requirements. There are currently no laws that limit suspension lifts, frame height, or bumper height. Residents are free to install truck lift kits, aftermarket wheels, tires, shocks, and bumpers. However, your vehicle needs to be in good condition before you hit the road.

Alaska

There are no laws covering a vehicle’s suspension, but the vehicle body must be no higher than three inches above the top of the frame. All aftermarket parts are allowed as long as they are in good condition.

Arizona

Truck and Jeep lift kits are allowed as long as you use mud flaps and fenders. There are no frame height or suspension restrictions.
