Rancho 2" Sport Lift and Rear Spring Rates

Good day fellow Jeepers. Just bought the Rancho 2" sport lift for my 2 dr 2008 JK. This kit replaces the front spring but uses spacers in the rear. I am towing a small pop-up (around 1400#). Noticed the front springs were 13's and the rear are 56's. The rear rates seemed to do well towing with the tongue weight of the trailer. I have had no problem and the pop-up tows pretty level. Should I think about replacing with a stiffer spring when I do the lift or leave well enough alone? I don't want to go through the effort and wish I had replaced.

Thanks

The 2 door kit lifts the rear 1.75
A 59/60 coil will give you more lift then you need requiring more parts. Id leave well enough alone.

kjeeper10,

I saw in a thread you mentioned to release the tension on the control arms after installation. Should I just loosen the bolts, let it settle and re-tighten? If so, do you know the torque on them?

Thanks for all your input.

It is never too late to do so yes. Loosen and shake/rock the jeep around. This just let's all the factory bushings relax, then everything is torqued at the new height.
All control arms except front uppers are 125
Front uppers 75
Tracks bars 125
