By Ben Brazda

Last updated:

D.C.’s street legal laws are not as complete as most states. There are no laws that restrict a vehicle’s suspension, frame height, or bumper height. As such, it is probably safe for drivers to install suspension lift kits, aftermarket wheels and tires, performance shocks, aftermarket bumpers, and grille guards.
