I currently have a 3.5” procomp lift but looking to upgrade for a better ride. My coil choices have been narrowed down to RK and Evo. I want to keep the same height but will be adding a new heavier bumper and a winch. I want to eliminate sag for an even rake.

My question is would it be better to get 4” coils in front/3” coils in the rear or the same lift coils but a spacer in the front? Any suggestions would help. Thanks

Copied and pasted from the other place you asked this.

Typically we use spacers to account for a Jeep that isn't balanced front to rear. Adding a large bumper and winch without similar rear modifications, tends to cause a lean forward, we would typically recommend a spacer before recommending a taller spring. That way if you eventually add a matching rear bumper/tire carrier/armor etc, you can remove the spacer and the jeep will be level.

Best to use a spacer. Measure your "unloaded" (before adding heavier bumper & winch) lift, then measure it "loaded." Add spacers on top of the front springs of a thicknes that approximate the reduction. FWIW, weight of my bumper / winch combination reduced lift height 5/16". I added 1/2" spacers and all was well.

A compressed spring with a spacer is still a compressed spring. Replacing with springs that will accommodate the increase in weight on the nose is the correct solution. Look at OME springs. OME makes springs just for this problem.

I would agree IF he is done adding parts to his Jeep. If OP were to add a rear bumper and tire carrier, his jeep would level out and the spacer would be removed which is free. If he opted for a longer spring the first time, he'd now have to deal with springs again.

"Form over function".....................

False, having the practicality of adjustment is not a form over function argument, it is a practicality argument. As I had previously stated, if he were done modifying the vehicle, we would recommend he go a different way but as he is not, we would wait until all weight is added first. We are not a company that is just in it for the look, we are a company that loves wheeling hard and we always will be.
