Each of these Race Ramps with 8 Inch Adjustable Wheel Cribs supports 1,500 lbs. and can hold tires up to 12 inches wide with diameters from 25 to 30 inches.
Adjustable wheel cribs are a two-piece version of your standard wheel cribs. Each crib comes as a stacked assembly of two interlocking pieces of equal height. Their design allows your car or truck to be lifted in incremental heights that provide clearance for a jack and a spacer.
Each set supports 3,000 lbs., yet each crib weighs only 7-10 pounds. You can use one set as either two 8 inch cribs, or four 4 inch cribs when the set is split.
