when you say "high speed damping" are you talking about large g outs/hard hits or chatter bump type stuff?
Large G outs and big hits. I’m content with the small chatter performance. I don’t want to make the small chatter any different, just add more valving for bigger hits. I’ve gone up
on valving 3 times now and it just keeps getting better.

have you tried upping nitrogen pressure yet or played with IFP location?

Don’t put that evil on me!!!

I’m kinda afraid that may be the case. Maybe TTB’s will happen sooner than later. Do you think Dana 35 stuff will survive under the XJ on 35’s?
D35 snouts are fine. Diff? Axles? I don't know enough about them to make that call. I have used the snouts and hubs on several 2WD builds for Toyota's to keep the same lug pattern.

if you go D44 outers for the d44 stubs and outer u-joints, they are pretty stout. the ring gear is about a half inch larger than the 30 you have in the front end but in an aluminum case. really, ive only seen exploders blow the outer stubs. once you upgrade that, not real sure. i would guess either the inner joint will go or R&P when rock crawling

Yes. Stock for stock everything in a D35 TTB is as strong or stronger than a D30 straight axle. U joints are the weak link in both. D35 stock locking hubs will blow up sometimes but those are a convenient fuse that take only a few minutes to change out. You can upgrade to the Warn ones to get rid of that too.

If you are really beating on it with a locker then you'll destroy shit on either a stock D30 or a D35 with 35's though.

I have not. The front shocks have bottom mounted piggyback reservoir. I’ve always just bottomed out the ifp then let it come up when I seated the seal head. Currently running 200 psi.

I like the idea of keeping my same bolt pattern. D35 makes the packaging way easier on the XJ chassis. I really only use 4x4 as a security blanket and mild trails. No real rock crawling. I have lots of reading on TTB to do.
