Softer than pucks.
There's some write ups online so I won't explain.
Progressives are nice, but I like the modularity and simplicity (and price) of the pucks. It's all preference, and it definitely doesn't hurt to list more options

I found a good deal on them that's why I'm running them.

For the rear I bought extended bumpstops and bolted them to some 2x4x1/4 box and welded the box to the frame rail.

I also use the Prothane Coil Inserts inside 'progressive rate' coil springs. For crawling the inserts are not necessary, hockey pucks work fine. But for faster stuff or drop-offs the inserts are the way to go, unless you can afford air-bumps. Inside the inserts is a 'rubber plug' for final bump-stop.
On the rear I prefer progressive bumps. Mounted on an extended backing plate that spreads the load. For contact on the axle I used a leaf spring perch that is also adjustable in height to match shock travel.
Do not have rocks where I live but I run 60 mph on a rutted beach and 20-30 mph hitting rows of camel humps that get the XJ airborne repeatedly.
1996 Classic, 5" lift. 10" travel shocks (6" up - 4" down). Bumps are set up to match shock travel and because of running fast terrain I use more up-travel than down.

I guess that would explain the trussed swaybar link bracket! Looks good

Thanks, that sway bar axle mount is from JKS, 2" extended. Stock mounts cause interference with the steering at droop (Currie steering). Allows for OTK also.
I had to learn how to weld to do that. But even with a grinder I could not smooth out those welds,HA.

That's a neat idea too. I have a 55 gallon drum filled with tennis ***** (don't ask) think I finally found a use for them.

If my jeep was dedicated trail rig I would definitely do it lol. But that would drive me nuts going to work at 6 in the morning everyday and hearing that on top of all the noises she makes.

Whats your experience with the prothane coil inserts. About half the wheeling I do is crawling but the other half is dune running. Often, the front of the XJ will go airborne or I'll just be hitting ruts fast and the front bump stops will slam together. I just put some 33"s under the jeep and so have even less up travel and need to build up the bump-stops. How well do the prothane coil inserts slowly dampen the jolt as the jeep comes down on them? Also, what size are you running? I have the same amount of lift as you so I'm just trying to get an idea.
