Any comments? Pics? Any sagging ?

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 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?

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.

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.

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.
