These set of Race Ramps have 8 Inch Wheel Cribs that can support tires with a diameter from 25-30 inches and a car weighing up to a total of 3,000 lbs.
Wheel cribs are a safe, lightweight alternative to jack stands. They cradle the tire 8 inches off the ground, providing unobstructed access underneath your car. Each crib supports 1,500 lbs. and weigh only 5 lbs. each.
Using 8 inch wheel cribs in conjunction with 56 or 67 inch race ramps allows your vehicle to be level while raised. This is useful for changing your oil.
