Trak Jax car ramps were inspired by an auto-crosser that didn want to buy a new, high-priced, low-profile jack just to change his tires at the track. These lightweight, durable car lift ramps get low cars up high enough to fit a standard floor jack under the car. At less than 5 pounds each and only 30.1?long, you can even fit them in the trunk of any sports car. Trak-Jax are available with or without a 1.5?stop.
