I've got a 6" pro comp lift on my 2005 Tahoe. I'm looking to raise the rear which is on coil springs.. never used the spacers on any of my trucks but like most have heard mixed reviews about them. I'm just looking for another 1 1/2" - 2" just to level it back out.. Don't know if all spacers would fit those springs as far as width??

Any input would be greatly appreciated!
