I'm doing a 2.5 inch coil spring lift with new shocks today and a rampage front recovery bumper and winch. I have a leveling kit already. My question is should I leave the one inch spacer in the back along with a one inch spacer in the front on both sides and put the lift on top of that or take the leveling kit off and then just put the lift?

 

Whichever you prefer. It will work fine in either configuration. You'll just have more lift if you leave the spacers installed. If you want to keep your center of gravity low, then take the spacers out. Can still fit big, meaty tires with only 2.5" of lift. Just have to trim the pinch seams in the rear wheel wells. Been running mine like that for almost 2 years with 37" Nitto Trail Grapplers.

 

I would just keep the spacer in the front to offset the weight of the bumper and winch you are putting on.

 

The spacers up front wouldn't be a bad idea with the added weight
