Each Race ramps with 12 Inch Adjustable Wheel Crib supports 1,500 lbs. and will 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 to be lifted in incremental heights that provide clearance for a jack and a spacer.
Each set supports 3,000 pounds, yet each crib weighs only 7 to 10 pounds. You can use one set as either two 8, 10 or 12 inch cribs, or a set of four 4, 5 or 6 inch cribs when the set is split.
