Spring ID

Our YJ came with a lift in it. The springs have RExxxx on them in white paint. I assume that indicates Rubicon Express? Fairly new stuff, however the shocks are Rancho 5000's. Ive removed one leaf outta the back hoping to soften things but its still pretty stiff of a ride for my tastes. Recon I need to beat on it.....errr. I mean them some more.

Check your shock length... RE springs tend to ride pretty darn good but if your shocks are the wrong length it's gonna be unfun....

Also make sure the spring eyes or shackles aren't hitting the frame... the 4.5" RE springs require +1 shackles all around w boomerang shape on the rear

I got off my duffer and looked up on Rubicon E's website and see that my springs are RE1430's. Why the Rancho RS5000 shocks I have no idea. There are RE greasable shackles at both ends, but the rears are not boomerang type. I've also checked for over tightened shackle bolts and frame rubbing and it all looks good.

8thtimer, leaf sprung vehicles ride rough compared to modern coil sprung vehicles. Our YJs are short wheelbase vehicles running on WWII technology with a couple minor improvements.
I suggest disconnecting your track bars and getting softer shocks. Running your tires with less air pressure might help a lot. I run 26 lbs on 31" tires that have a stiff sidewall. Google "chalk test".
Some posters might suggest disconnecting your sway bar. I don't suggest that if you drive the Jeep on the highway.

The RE springs are quality springs and I don't think you'll find any that ride better, with the exception of OME springs. Since you already have the RE springs, I wouldn't spend what the OME springs cost in the hopes of a slight improvement in ride.

A rough ride is subjective. I have stock height heavy duty springs with mid grade NAPA shocks and I'm happy with the ride. Does my YJ ride as smooth as my extra cab, long bed F-150 or Mrs. Lucky's SUV. Of course not.
For me, I'd do what I could to soften the ride and once I did that, I'd just live with it.

Good Luck, L.M.

Im not running either the sway bar or track rod on the YJ. Being I only putt it around a few miles into town or across the road in the NF trails. I was running 20 psi on the rock hard really old Mickey T tires. Even at 20 or less there still rock hard from age probably. I need to replace them eventually, but Im retired and on a budget ya know. I was surprised to see the RE1430 springs are only 2.5" lift. based off the other CJ/YJ/TJ I was thinking 4". But for my needs its perfect just how it sits. maybe some Bilstein shocks in the future??

86 the bilsteins...

Are your shocks rs5000 or rs5000x?
The former are very hard but the latter are considered by many to be about the best riding shock available.

The 2.5's don't require boomerang or even longer shackles....

I haven't riden in a yj with the 2.5 standard duty springs but I had the extreme duty 2.5's on my 94 for years and was just amazed at the ride quality.... better than a stock tj... my 4.5" eztreme duty springs on it not may not ride quite as well as the 2.5's did but they are still great.... as good or better than my stock tj.

I have the re1430's front and back, while they are a bit stiffer than my old stock ones, the ride is pretty crisp on pavement, but they literally handle like a sports car, off road, anything under 15-20 mph is bumpy, get over 20-25 and I wouldn't trade them for anything. Can't compare the rs5000x shocks against any others since they are the only shocks I run on anything for off pavement. best bang for the buck IMHO...
