Rear axle lowering blocks for a C20....

Does anyone know where I can get some that actually fit. Most say they fit, but with the fatty rear end on the 3/4 ton...the don't fit. Anyone know where I can get some from? Thanks!

Re: Rear axle lowering blocks for a C20....

What differential is under your C20? The trailing arms are interchangeable between C10's and C20 as well as the U-bolts, so I don't understand why the typical blocks won't fit. Unless your truck has a different differential under it. I doubt that anyone makes lowering blocks specific to a C20 so if need be you will likely have to have some made to fit your truck.

I guess I should have been more specific. The blocks are not the problem, it's the U bolts that are the problem. The U bolts are too small (narrow) and do not go around the axle. If I could just get U bolts that fit, that would be great.

Any local spring shop should be able to make you new U bolts.
