HELP! 3" lift RCD Progressive Rate Front Coil Springs

06 TJ, Rubicon Series. RCD put stickers/labels on a coil on their springs. I think the labels are up-side- down. With the labels orientated with words up-side-right, 4 coils on front springs are bunched closer together at the bottom. Shouldn't the bunched-up coils be at the top on a progressive rate spring? I'm thinking of pulling and flipping the springs with labels up-side down. If the coils bunch up at the top, I'm thinking leave the springs that way, with labels upside down. Off the jeep springs are indistinguishable top or bottom. Please save me some re-installing time and convince me the progressive rate spring coils should bunch up on bottom instead of top, or that it just doesn't matter...

from my limited knowledge on coils and a quick look at an extreme terrain kits instructions where they say to put the bunched up ones on top i think to have them work as intended you do have to flip them over but again im a leaf guy so only take my words so far

i dont know about RCD but theres generally only 1 way to install front coils on a TJ, little pigtail at the top. meaning the coil diameter is smaller at one end than the other. the little end goes up top and the wider end goes on the bottom.

don't think it matters where the spring bunches up, when weight is removed it will expand whether the bunched up bit is at the top or bottom

Thanks for replies. I think I'm going to flip them. I'll double check for pigtail but was told the ends of coils were identical off the jeep.

The fronts only physically fit one way. The rears can be flipped. Beyond that, springs do not care what direction is up. The will work the same.

It makes no difference and progressive rate coils make no difference either.

But the stickers are upside down. Everytime he crawls under the Jeep, the OCD kicks in. I remove all stickers on mine or just flip them over.
