We also recommend that the installation be performed on a firm, flat and level surface, such as seasoned asphalt or concrete. The use of safe and properly maintained equipment is very important! In order to document any possible irregularities in the factory ride height of your vehicle, please take a few moments to fill out the Belltech Vehicle Inspection Record included with these instructions. 1. JACKING, SUPPORTING, PREPARING THE VEHICLE a) Block the front wheels of the vehicle with appropriate wheel chocks. Make sure the vehicle’s transmission is in “Park” (automatic) or 1st gear (manual). Activate the parking brake. b) Using a properly rated floor jack, lift the rear of the vehicle off the ground. Lift the vehicle so that the rear tires are approximately 6-8 inches off the ground surface. c) Support the vehicle using two (2) support stands, rated for the vehicle’s weight. The stands should be positioned, one on each of the frame rails. Prior to lowering the vehicle onto stands, make sure the supports will securely contact the straight, flat portions of the frame rails.! It is very important that the vehicle is properly supported during this installation to prevent frame damage and personal injury!
