3" x 30" Trak-Jax Ramps (RR-TJ) by Race Ramps®. Trak-Jax ramps were inspired by an auto-crosser who didn't want to buy a new high-priced, low-profile jack just to change his tires at the track. These ramps lift your car 3 inches so that you can fit a standard floor jack underneath. They're small and lightweight at only 5 pounds per ramp, so you can easily toss them in the trunk of your sports car for your day at the track. They can accommodate tires up to 10 inches wide, and support up to 1,500 pounds per ramp.
