I have my kit coming tomorrow along wih a expedition one rear bumper and tire carrier. Since the RK is made to level out the Jeep and I'm putting on a rear bumper and just a stock stubby front should I order some spacers for the rear springs? If so what size? Thanks guys

 

I have the 3.5 with the expedition rear and a very heavy 35 hanging on the back. Don't believe you will need a spacer. Those springs can take the weight.

 

That is one of the advantages of RK's progressive rate springs I added a heavy rear bumper, heavy front bumper, and winch and I dropped 1/4-3/8".

 

Just get a winch to even it out

 

Personally, I'd try it and see, but I'll tell you that the Jeep below is running RK's 2.5" + .5" spacers in the rear:


There's a winch on the front, the front bumper isn't overly heavy, and the tire carrier you can see.

 

I definitely am planning on that!! Just not right away.
