Rack Ramps from Race Ramps are the perfect solution for getting cars with low ground clearance onto 4 post workshop lifts. They are much lighter than the ramps that are supplied with lifts and are incredibly durable. The composite construction and textured surface means they won't slide on concrete or painted workshop floors either. There are two options of Rack Ramps available - RACK 4 - Suitable for use with 4 post lifts that have a permanently attached ramp. A notch on the front edge accommodates the original ramp and with the rack ramp the run on angle is decreased. Specs - 27.5" long x 4" high x 14" wide. 9 degree incline Weight - 10lb (4.55kg) each ramp. RACK 5 - For 4 post ramps that have no run on ramp. A lip on the front edge bridges the gap between the Rack Ramp and lift platform. Specs - 40" long x 5.75" high x 14" wide. 8 degree incline Weight - 10lb (4.55kg) each ramp. Sold as a pair.
