Aside of the obvious 2.8degree tilt of the DPR rails, what is the difference between the Edge rear and the DPR rear? I mean general dimensions and locations of components: arms, shocks, idlers?
Would it be possible to take an Edge supsension, and bolt on 136 or 144 DPR rails, or would they bolt onto an xc-10 suspension easier,if at all?

As far as the Edge is concerned, I can tell you that the rear trailing arm components are located about 2" further back on the 136" conversions, compared to the 121".

What are you thinking about doing?

144 DPR rails on a 95 XCR. I just figure it would be easier to find a complete edge or xc-10 susp, and throw on the DPR rails, if possible, rather than trying to locate a complete 144 DPR skid.

I can't believe I didn't get any help on this!
I was at a dealer Friday, and looked myself. Entirely different. Edge doesn't have a rear scissor arm. The lower and of the lone rear linkage is in slider blocks that move in a slide space in the rails. The DRP susp is very basic, and looks like any other rear end from 6-7 years ago.
