Rear Leaf Downtravel / Do I need new shocks?

Hey guys,

I just added JKS shackles and relocation brackets to my 1999 XJ rear suspension (OME leafs and OME 60053L nitrocharger sport shocks).

With the additional equipment, my resting length is 22.5" of the 24.5" max extended shock length (no BPE and stock axle mounting on Chry 8.25).

I assume this will result in insufficient downtravel capability (~2") but would appreciate your input.

Also, I've felt the OME nitrocharger sports have been stiff onroad when fully unloaded. With all my camping gear, its much better.

Therefore, any input on new shocks (if needed) would also be appreciated.

Unbolt shocks at the bottom, flex to the max with whatever you have available, (I use a forklift) and observe where the shock mounts end up at full drop.

Do you still have a rear sway bar? It's become the first thing to go when I get in the back of one.

The rear sway bar has been removed.

Below are images showing the process you describe. The distance from the shock axle mount point to body mount point is 27" just before the tire comes off the ground. (shock extended length is 24.5")

Re: Rear Leaf Downtravel / Do I need new shocks?

your shock is definitely limiting droop with your new setup. shocks neither like to be limit straps nor bump stops. luckily, the leafs are a natural limit strap.

you can relocate your axle side shock mount to make more use of your shock, but that is only half the equation.

i would suggest setting a positive bump at full compression. then from there you can evaluate... will relocating the shock mount be enough, or do you need to purchase a new shock as well. or does bolting a new shock in fix your problem entirely? either way... i would still suggest a positive bump.

You'll get more drop to one side if you tuck a wheel on the other.

In other words, pick it up by the wheel/axle on one side and look at the other.

Measure extended and collapsed length for travel.
And find correct size shocks for your application.
