Hey @TerraMechE your truck is so sick. Can you elaborate a bit more on your rear suspension setup? I know you've since moved on to 14" Kings with a bed rack. But for this build with the Bilsteins, what did you have to do to mount the new Jeep leaf springs? Was it "just" mounting the new leafs and then doing the spring under conversion and new shocks + bumps? or was there there more customization that you had to do? How much travel and lift did this give you? Thanks!

I just got my truck a few months ago and I'm trying to decide what to do with the rear. I want to understand what's the best setup you can get without doing a bed rack, and I think yours is it . I'm only on 33" tires btw.

For use with the stock damper mounts, I found dampers with the longest stroke that would fit in a collapsed state with the increased up-travel of the spring-under setup with shorter Raptor F150 bump stops.

The dampers happened to be Bilstein AK7110SB (7100's, 10" stroke, short body... about 14.29" inches collapsed). I replaced the spherical bearings with urethane bushings one these, as well.

Side note: these dampers were fine for most things, but not stupid things. Doing mach-chicken for miles on washboard roads with heavy valving, I overheated the IFP and the expanded glass-fill plastic seemed to tear up the inside of the reservoir at one point. I repaired them with a steel IFP and didn't have the same problem again. They were just limited on how much damping they could make. This was not the damper's fault; I pushed them outside of their intended use case, hence the move to the bigger dampers.

I welded on leaf spring perches to the bottom of the axle tube.

...and had some shackles laser cut to the length I needed and also to clear the rear frame

I think that's about it.

I continue to mess with this thing. Ford 9" rear axle is next... I need a more robust, wider axle housing for jumping.
