But, like I said, you need to stack some bead on two sides to keep them from spinning. Link to comment Share on other sites More sharing options...

Definitely go a little longer if not going stock. Had to raise the bed a little for body lines after installing poly bushings and the stock bolts weren't any too long.

kramttocs Posted May 30, 2020 Share Posted May 30, 2020 What do you think caused that Scott? Stiffer cab bushings than 'normal'? That has been my guess. I didn't measure the 35yo factory ones against the poly before installing them but I know the poly were a LOT harder. They also didn't seem to compress at all when torquing them down (again, didn't take any measurements). No complaints in the ride factor though.
