Has anybody here used this kit? I just want to get the rear leveled down some. Trying to keep it simple, cheap, and not sacrifice any ride quality. I know right now if I hit the gas hard at a light my rear bump stops hit. I do not want to aggravate that at all going lower. Need some direction. Thanks.

Them coils are likely the same as what I ran on mine during all my lowering testing. IIRC, they dropped 2.5". They rode about the same as stock, maybe a little softer.

If you can hit your bump stops now, then lowering will just make it that much easier to hit 'em. You should do the free travel mod.

Your rear is 2" higher than the front?

Yes It has a rear factory rake.

I asked cuz it doesn't look 2" higher in your sig pic, but it could be the angle.

I think mine was right at 1.5" higher, but my ALC was also not functioning and it's supposed to lift it about .5" after startup.

If your rear is compressing far enough to hit the bump stops from factory height just from hard throttle, then your springs are shot.

I’m in the same spot as OP I have a 13 with wz7 suspension and it sits about 2” higher in the back. It’s 2wd and I want to level the rear and not lose my towing I was going to do the kit mentioned and keep my nivomats shocks what do you think?

From my experience, I think the coils are close enough in load capacity to the factory ones. Having a functioning Auto-Leveling system will help keep you from bottoming out, but you will have to shorten the link rods on the sensor arms. If you don't, the system will think you're sagging 2" in the rear and will try to air it up to compensate, making it ride very stiff in the rear. I suggest removing the bumpstop and its bracket (the "free travel mod") for towing purposes. Usually, this is only necessary for a 3" or greater drop, but the rear will compress further when towing. Get your sensor links adjusted properly and you'll get your drop and likely not feel a difference or lose any load capacity or suspension travel.
