The rear shocks are for the 4" lowered application, so it shouldnt be those holding up the rear.

I went from the 4/6 to the 2/4 just to get some of the ride and suspension back. The tires fit perfect unless i had like 5 people in the truck then they would rub on the driver front if i hit a nice bump. I just wanted to gain some ground clearance, and stuff. Looks like the front only is one inch different after the swap, but it needs to come back down in the back. Looks like im in the market for a 2 inch shackle.

 

Did you measure fenderwell height before and after? Is it possible that the spring rates are wrong, like a regular vs. extended cab spring? Might not be much help but its a thought.

 

They only make one spring package for our trucks. The only thing different in the kits for the single cab and ex cab is that for the ex cab they provide a carrier bearing spacer for the driveshaft. Speaking of which, i thought i heard of someone using a one piece shaft from a z71 or something and that it was a direct replacment?

 

Ok, I was thinking that the rear springs were different; I knew the fronts were the same. Also, wouldn't a Z71 shaft be shorter because of the transfer case?

 

I just thoght i heard of someone using a one peice.
