The first kit on the JKUR we had was just Rock Krawler 2.5 original design springs, shocks and brake lines, bump stop extensions, everything else was completely stock and it was good for a cheap way to gain altitude and maintain somewhat stock ride. The first kit on the JKUR was alright for cost, you can't expect the world realistically.
Then I upgraded to the complete X-Factor Mid system with those 2.5 springs. It was still nice but better off-road for sure with the incresed flex and not always puking out rubber control arm bushings every other wheeling trip.
And now they are the newer 3.5 progressive rate springs that are supposed to ride even better than the original release springs. They do ride nicer and the difference is especially noticed going from empty Jeep to full week provisions camping load. No complaints here either way actually. Handles the Jeep loaded with a weeks worth of camp gear and all 5 of us fairly well with minimal signs of sagging when max load out and still smooth with just me or the wife.
I have owned 12 Jeeps over more than a quarter century of all types so I have some experience with them. Jeeps we own are not pillow barge mall crawlers or soccer mom SUV's. They are not show trucks with chromed out lifts to the moon either the way we build/use them so I don't expect the Cadillac Escalade type of ride from any of my multi-purpose Jeep 4x4 builds. We actually wheel them over trails like Fordyce, The Rubicon, Dusy-Ershim and Swamp Lake. We occasionally go to JV and play where KOH is held but don't go too crazy cause we want to be able to drive to work on Monday morning LOL.
Shocks we've used:
Rancho 5000/9000
Pro-Comp ES1000/3000
SkyJacker Hydro & Gas Charged
RE mono's and remotes
Both Bilstein 5100 series
Fox smooth bodies & remotes
Later came the Kings with German car dual rate sliders.
BOTTOM LINE FOR ANY LIFT HERE IS:
Really happy with it overall now but one word of advice if anything no matter who's suspension you choose:
*****Don't go cheap on the shocks, they have a HUGE impact on ride quality overall.*****
Shocks make a big, big difference in ride both ON & OFF-ROAD, so choose carefully and wisely for them to be properly valved and match tuned to your Jeep.
