No such thing as to much flex this statement doesn't compute LOL

If you end up changing the shocks you can get a set sized up properly to prevent that. Might want to recommend that to Marlin actually since he has those 7100s built.

hahahah I vote for getting limiting straps and let them take the abuse of stopping the axle from dropping. But like matt said let JBA know, a solution should ship with the kit.

Well the lift still has a inch to gain so that might help a little. Theres usually a few spots where a tire will come off the ground but didnt happen today

now i just have to fix my mirror:confused:

I think you'll find the normal spots that were hard or scary no big deal now. You'll have to pick harder lines now I noticed that when I wheeled the XJ picking the same lines I did with my XK was not cutting it and I had to adjust in my mind what was passable now.

Well... Limiting straps would do it, but ideally, that is the primary purpose of the shocks.

I had always heard that you dont want to use the shocks as limiting straps

Its easier to "fine tune" the maximum extension of the suspension with limiting straps since you can't exactly order shocks in 1/8" increments (for the most part anyway). But there's nothing wrong with having the shocks limit travel.... that's how every stock suspension is designed.

There's always exceptions to the rules... like prerunner trucks that are aways catching air; you don't want the suspension continuously bottoming out the shocks on every jump and you don't want the shock at its limit when it has to suddenly dampen the suspension when the truck lands.

But for what we do with these vehicles, its no big deal.

I've seen some badass vehicles get stuck several times. It happens. Just got to be happy that you can go places you couldnt several months ago. And im sure the added ground clearance helps out a lot!

I've only heard speculation as to why.

I'm not sure why Jeep stopped doing this with the WK, but the RSA config's in the past (those using coils) used clips at the base of the coil to fix it to the axle to keep the coil from coming out.

Its fine for them to be used as limiters for Down travel (except for those fast running comp / desert racer trucks) but not for up travel, need bump stops for that. If you are dropping coils out then you need straps, longer bump stops to retain them or simply fix the coil to the diff.

Looks good Jager, hows the pinion angle on flex etc? I notice they have used the factory upper mount with an adjustable arm and i assume SL bracket on the diff?

I have been wheeling pretty hard and have not had the rear springs reseat improperly. They always fall back right into place so I don't think loose springs is an issue, though some longer ones would be nice.

What is an issue with the XK during hard flexing is the drive shaft rubbing the fuel tank skid and bending the lip up enough to tear the rubber boot over the spline. Is it the same with the WK?

Only for those who start adding spacers on top of a 2.5-3" lift and don't make the necessary modifications. But yeah - it does happen.
