I installed my 2.5" RK in March of 2015 and my rears sagged after I did the Rubicon Trail fully loaded. Up until the loaded trip they were fine and had done a lot of offroading just not fully loaded down. RK had me send them some measurements to confirm they were indeed sagged and took care of me pronto. I love the way the ride on and off road.

I did the 1.5's and am very happy with the ride and height. Haven't noticed any sagging in the 6 mths they've been on and I've hauled quite a few bags of cement!!

Anybody able to compare these to other springs from experience?
I have Rancho 3" springs and they're a bit stiff for me, so I'm trying to see what would be a good replacement.

I am getting ready to swap out some linear TJM springs for some RK progressive. Linear springs will always be stiffer than progressive, unless the spring rate is reduced in the linear. My thoughts any way.

That's what I'm thinking. Let me know how much the ride quality improves when you switch to progressive coils!

I have the 3.5 triple rate. After I installed the heavy rear ace bumper and 37 tire it squatted the rear a bit and the front is very light with a stubby ace bumper no winch. I bought a TeraFlex 1" rear coil spacer I'm going to try to see if that will set me closer to even. They ride very nice the few miles I've put on so far. I believe the rear springs are just lowered down from the weight portion of the triple rate to the ride portion now. Here's a pic of the squat I'll put the spacers on this weekend and update a pic.

I want to hear more about this. They lost lift due to weight in the rear? How long was it loaded? I think I've put close to 800lbs of sand in the trunk. What are measurements good and bad?

When you do the rubicon trail you need to be self sufficient for 2 or 3 days so you are pretty well packed to the hilt ie coolers, tools, etc Not sure how much weight there was but I suppose a couple hundred extra pounds. was my wife and myself. I had put around 10-12000 miles on them up to that point with no issues and had done a fair amount of offroading including the San Juan area of Colorado and many local trails. When I was in Colorado we had a base camp so most of the heavy stuff was left in camp when actually jeeping same for around home as no need to be packed for 3 days etc. When I returned I noticed my rear was sagged more than it had been and it seemed every time I measured it I was a little lower, I ended up installing a 1" spacer which got me back to pre rubicon trail height, but it was not long and again I started sagging more. I contacted RK and they had me take photos and measurements etc and they replaced my rear coils. all is good again. they are a great company to work with. I do not know if it was the hard offroading with a heavy load or just bad luck. either way RK took care of me. If you think you are sagging I would suggest contacting RK and they will tell you where to measure.

Adding weight also puts the triple rate coils in a softer setting. Drivability is much better IMO with added weight as opposed to stock weight.

Looks good!! I just installed the RK 2.5 Flex kit and still have almost a full inch of front end rake and a nice lean on the right front corner a little over a 1/2", no extra weight other than a 35" on TF carrier on the rear. Interesting to see yours leveled out perfectly.

I seen other brands of springs sag and Jeeps have the lean to the right side. This isn't a RK issue. I believe this has to do with the Track Bar adjustments

My axles were/are perfectly centered and it was a rk issue on mine. I have no side to sign lean but my rear dropped 2" in a short period of time after being consistent fo 10-12000 miles. Once it started it was evident which was not normal. Jk was great to work with.

Sagging issues makes me wonder what type of metal is being used for the springs. The spring is supposed to return to its original length.

Only RK product on my lift is the springs and they've been sitting the same for past 2.5+ years (or from what I've noticed). No complaints here
