Hello,
So after reading that 89 springs are the stiffest and offer the most (but still small) lift for our front stock springs. I was just wondering if it matters which z71 rear spring to buy?

There is only one stiffness of the 2007+ Tahoe/Avalanche rear springs. No choices on that platform because a rational design team worked on it. Not the children with inadequate adult supervision that did our platform and the very similar HHR.

I just installed the Z71rear springs on my 97x 5.3 and it drives great. Installation was easy. Yes, i removed the fuse.

What's the part number for those z71 rear springs and did you use the 2" blocks too?

I dont have the part #. I did not use the 2" spacers. I just have the new Upper control arm bushings and front 3" spacer. I am waiting on the front shock and springs, then I'll install it all and decide then if I will install the rear 2" spacer or not.
