the timbren spring stops will work, but they are kind of long and need the lift to maintain some semblence of spring travel before getting into the rubber part.
I shortened my mount a bit, and have two sets... one which is short and fits well at stock height, but a very hard hit still slams some.....
and the full short spring, which will not slam ever, but engages kind of early on during suspension movement without the lift. Have plans to try out some kind of modest lift soon, I just would rather avoid any VDC side effects...we'll see.
I have a few new photos of the bumpstop combinations I made up..let me know and i'll put them together in one post.
