Hey, only just saw this. Measured up the shocks and bump-stop clearance while I was fitting them up, and it looks to be okay.

Shock Length (in vehicle): 515mm
Shock Length (Closed): 375mm
Bump Stop Clearance: 90mm

So I've got about 140mm of shock up-travel with 90mm of bump-stop clearance. The 50mm of bump-stop compression should be more than enough, especially with them being polyurethane.

Anyway, I ran the original monotubes and the custom shocks on the dyno at work yesterday, and the valving is just right. On compression the new ones are a little softer to acommodate the higher spring rate used to get the lift, while being about 1.5x heavier on rebound for the same reason. A little more gas pressure than OEM for stability, and it's riding really nice.
