07 Sierra Z71 Cheapest/Easiest Way to Lift Rear 1"

07 Sierra Z71 Cheapest/Easiest Way to Lift Rear 1"

Postby ZakBradshaw [OP] » Apr 14 2013, 7:51pm

I just bought a 2007 GMC Sierra 1500 Z71. I wanted the leveled look so I was told the 2.5" front coil spacers would level it out. I just put those on and had an alignment done and now it seems the rear is about 1" lower than the front. What route should I take to raise the rear 1"? When you look at the truck, you can't really tell. I measured the gap, and since I know, it's bothering me. Also, what is the biggest tire I can fit on this truck with the 2.5" front and 1" rear lift? I have the stock 17" wheels. Someone said 285/70/17. I just want the biggest tire I can get without trimming or rubbing. Thanks for everyone's help. Zak.

Add inch lift blocks to rear blocks or buy new blocks an inch taller nod 285/70/17 fit with no problems.

One inch eBay blocks will be the cheapest route.

Will a 285/75/17 fit?  That's about right under 34x11.5.  I'm looking at a 1" rear block kit on EBay that comes with longer u bolts for $50.  Would this be what I need?

It's not recommended to stack blocks. I would either look for a 2 or 3 inch block.

Which block will get me a 1" lift? Anyone running 285/75/17's on stock rims with a 2.5" leveling kit?

Alot of people say not to stack blocks but you're not going high so I wouldn't worry about it. Before I lifted mine I had and one inch lock stacked on mine and had no problems for two years. As long as the u bolts are tight you'll be fine. If you were stacking 5" blocks it would be a different story.
