I’m not driving an xj but my wj has 4.5” lift and I put bilstein 5100’s on it shortly after the lift. I had whatever shocks that came with the initial lift kit but they were junk. It’s on short arms so the suspension is pretty abrupt and violent on big bumps. The 5100’s are nice if you’re looking for heavy hauling and fire roads.
Owner reviews for shock absorbers
I use them and really like them, and I have only an upcountry lift, so close to stock. if anything they're a bit on the firm side, so they are def more stable, controlled, and connected. They don't totally remove the bumps, but I much prefer them to the monroes.
Love my Bilstiens, was night and day vs the factory style shocks even though they were only 3yrs old. Biggest difference is on gravel roads especially with a heavy load.
Love my Bilstein 5100s with my 4.5 inch lift. They have been on it for 5 years now and still do the job in ten sand dunes. No shock fade. Yes on road they are abrupt compared to your parts store junk like Monroe.
Highly recommend Koni shock absorbers, they are amazing on corrugations, can sit on 100km/h easily.
I use Bilstien on my truck
Bilstein B4 are good. B6 are better.
My main goal adding the Bilsteins was to correct the sloppy ride of the stock rancho shocks.
Bilsteins obviously are great. My friend put Bilsteins on his and it's a bit stiff for a daily driver without a lift, imo, but you might not have the same problem or might not care as much lol
I had the Fox 2.0’s and the shock shaft wore through the top mounting plate.
