New Jersey Lift Laws and Vehicle Equipment Laws


Although New Jersey allows for vehicle modifications, they give bureaucracy a whole new meaning. Almost any modification that alters the way a vehicle drives will require a vehicle safety inspection and certification. As long as the vehicle is able to pass the certification, suspension lift kits, aftermarket wheels and tires, performance shocks, aftermarket bumpers, and grille guards are allowed.

Breaking News: The New Jersey Assembly Budget Committee voted to eliminate the mechanical inspection program. No word yet as to when this will take effect.

Update: Effective 8/1/10, New Jersey no longer requires mechanical inspections for passenger vehicles, however, Elevated Vehicle Inspections are still required for lifted vehicles.
