Rubicon Express 2.5" lift with Fox Shocks

Does any one have a Rubicon Express 2.5 coil lift with Fox Shocks and not install the extended bumpstops? Since I do not have over 33" tires I would like to not use the extended bumsptops to get more travel.

Jeep - 2014 JKUR

Lift - RE7141

Fox shocks - 985-24-015 1.5"-3.5" lift

Fox shocks - 985-24-016 1.5"-3.5" lift

I was able to find the compressed and extended lengths of the shocks. Does any one know the compressed maximum length or has used shocks that have the same or more length without using any bumpstops?

FOX (Front) 985-24-015
Extended Length - 24.800"

Collapsed Length - 15.200"


FOX (Rear) 985-24-016

Extended Length - 24.450"

Collapsed Length - 14.850"

So you want more up travel at expense of down travel ? That makes no sense

The shocks you have listed are rather short.

Was thinking more travel is better but do not want to over compress the shocks. I was only able to find the compressed\extended lengths on Northridge 4x4 not from Fox's site. From what I have read, down travel is more important. Why would it limit down travel?

I was looking at the shocks (specs) you listed.

The stock rubicon shocks are
Front 14.75 collapsed 22.85 extended 8 travel
Rear 14.63 collapsed 23.13 extended 8.50 travel.

So for example a shock that's 15.75 front and 15.63 rear collapsed will require 1" bump stop.



Take a look down this list to help you decide.

Ok, that makes sense. I searched a bit more and found Bilstein 5100s for up to 3" lifts have about the same travel. Shocks for a 3-5" would have a longer extended length but would require bumpstops. Sounds like the shocks might work without bumpstops but might over compress. I will do a little measuring and may try it without bumpstops( test after). If installing the bumpstops I lose 1.5-2" of up travel, will be noticeable off-road?

Depends on your style off road.

Took some quick measurements. Looks like I should have 1" bumpstops to be safe. The lift came with 2" bumpstops. Think I will just use the 2" bumpstops.

I installed the bumpstops. When searching about steering stabalizer recolation mounts, found that bumpstops may be needed when when mounted above the tie rod.
