Rancho RS5000X Shocks

[JMT]

I'm looking to change out shocks pretty soon. Right now I'm running Rubicon Express Shocks that came with a 1.75" BB. When I got rid of the spacers and went to my 2.5" OME, I just did the coil springs and kept the shocks, assuming they would be alright. I called RE and found out the shocks were Bilstein 5100 with extend/collapse values of 23.5/14.9 Front and 23.8/14.8 Rear. This is the proper shock value for 3.5-4" of lift! I have no idea why they sent them with a 1.75" BB.

In any case, I'm looking to ditch them and get the Rancho's. What part numbers are you guys going with?

OME Shocks designed for my shocks have these values

22.42/13.15 Front
22/13.3 Rear

Closest I could find are these. Confirmation? Other opinions?

RS55319
22.42/13.76 Front

RS55260
21.540/13.640 Rear

I got these and love them. Not sure on the numbers.

I run the RS55239 front (23.8/14.4) & RS55241 rear (21.6/13.6) with my 2.5" lift.

Those Rancho part numbers you posted don’t look like 5000X numbers.

For your 2005 TJ, 2.5” Lift I’d go with RS55239 front and RS55241 rear.
You could also call Rancho to confirm.

I’m looking here:

I just put 5000X numbers 255 & 256 on mine. For the 4” Lift. Only have 80 miles on them but so far they are much better than the ProComps that came on it. I ditched the boots, but that’s just my preference.

I am at 2.25 and used the 55239/55241, same as @CodaMan. They can do 3" easily so they should work for your set up.

 

[CodaMan]

According to Rancho those numbers you posted are RS5000X shocks, however they don't fit a TJ.

I just ordered a set last night for the front, I got the 128. I'm hoping there as good as what I've read

I'm running same as @CodaMan and @Rob5589, RS55239/RS55241.

Yes sir RS55239/RS55241 is correct. Just went over this yesterday to get proper set up for 3” lift.

I had a post not long ago. Shocks. The good the bad the ugly. On the second page Chris has an Amazon link for the Ranchos for the 2-3” lift and Serbonze has the correct part numbers for the 4” lift. The company I bought them from recommended running without the boots. He said they accumulate dirt and water in them and then rust. I’ve been out of the country almost since putting them on so don’t have an educated review yet. Initially they seem good. A street to work as a lot of lifted spots due to tree roots. That area feels smoother. Haven’t gone off road enough to know how they will do.

I'm waiting on mine to come in, I got the ones for 0" lift. If I end up putting a 1.5" spacer lift on should I be able to keep the same shocks

I wish I could answer that. I’m not familiar enough with this yet. Maybe 1 1/2” is not a thing. But, I would wait for someone who knows what they’re talking about to answer your question properly.

No. You'd need new shocks. Many BB's (spacer lifts) come with shocks. Other spacer lifts are simply folks trying to solve sagging springs or leveling issues due to greater weight from a winch or bumper, which is not really making a change, just trying to get it where it should be. But you are making a change.

Here's how it works. The springs are what hold the weight of your Jeep. The shocks control the response to the terrain as the Jeep goes down the road. If you hit a bump the springs alone would cause you to have a very bouncy ride, but the shocks stop that by valving which returns it to normal ride so you don't bounce all over the place. Shocks determine your ride quality. If they are too short, as yours would be, they will not be long enough to function correctly controlling the bounce.

Think of it in terms of shock travel. Say you have a shock that has a 10" travel length. At ride height, this shock is setup to have 5" uptravel, and 5" down travel, giving it plenty of movement in either direction to handle certain road events. You raise the jeep 1.5", you now have a shock that has 3.5" of uptravel and 6.5" down travel, so the shock now has less travel to handle an upward event. You need balance.

Thanks, I'm between a budget boost or tube fenders. Since I already have new shocks I'll probably just replace the fenders
