These are a pair of brackets selected out of our complete 72-93 ram coilover, long travel air, and coil conversion suspension kit, in case you want a set to build your own link design suspension or use a different axle than we did and take advantage of this bolt on part, designed to utilize as many original frame holes as possible. It is meant to clamp between your original 4x4 transmission crossmember and the frame. 3/16 and 1/4” material, more than strong enough to beat on. We’ve used this on old dodge trucks, squarebody Chevy and more.
