Wheel Cribs are a safe, lightweight alternative to jack stands. They cradle the tire 8, 10, or 12 off the ground (depending on the model), providing unobstructed access underneath the car. Each crib supports 1,500 pounds (3,000 pounds per set) and weighs only 5 pounds. Using 8 or 10" Wheel Cribs in conjunction with 56 or 67 Race Ramps allows your car to be level while raiseduseful for changing your oil, for example. Wheel Cribs also can be used for car display and are available in custom sizes. *You must use Wheel Chocks behind both tires on the Race Ramps before jacking up your car to place the opposite two tires on the Wheel Cribs. Pit Stop USA offers Race Ramps Wheel Cribs - 8" Height - (Set of 2) RR-WC-8 at low everyday prices.
