Utah Lift Laws and Vehicle Equipment Laws

Utah has some of the best off-road trails in the nation and although there are no suspension lift limits, there are strict frame height regulations. Luckily, as long as vehicles remain compliant with this law, suspension lift kits, aftermarket wheels and tires, performance shocks, aftermarket bumpers, and grille guards are allowed to be installed on vehicles.

Governing Laws


The Utah Code (UC) governs the state's street legal laws.
