Upper rear shock mounts?

[Recon!]

It is a common problem area. If there was a design issue that was overlooked it was the bumpstop. There is a metric assload of flex in the rear, so it's pretty easy to fully compress the shock before the springs are maxxed out, and on the opposite side it's equally easy to fully extend the shock before the spring hits full droop. Both scenarios put a lot of stress on the upper shock mounts.

Inboarding helps address this problem because you have much more 'room' for longer shocks with the ability to choose the upper location that gets the shock in the sweet spot.

Longer shocks in the stock location helps with the droop side of the problem, but they will bottom out a lot faster. The factory bumpstop is pretty much useless when the axle travel is extremely articulated. It misses the upper spring plate by a lot. Even extended bumps tend to miss in that situation. It appears the bumps stops from the factory were meant to hit their targets when the entire diff compresses.

So what do you recommend for bump stop mods? I'm planning on a 6" spring lift with 37's.

I don't have the answer, other than to inboard the shocks and set them up so max droop and stuff doesn't bottom them out or fully collapse them. The difficult part is you can set up bumpstops for controlling articulated travel (truck twisted up) or regular full compression (compressed during a very bad bump) but not both. Leaf spring rear suspension has a lot of axle steer...which is a lateral movement of the diff as it articulates. Usually several inches laterally.
