Does anyone know if using Superlifts 4" blocks instead of the 3" blocks that come with the 4' suspension kit would pose a problem in the rear? Axle wrap issues?
I'm thinking about doing the ORW Coilover conversion when I do my Superlift in a couple weeks and saw that Summit has them for like $20 more. Any help would be great on this...specs on my truck are in my sig.

 

I wouldn't use 4" blocks, or even 3" for that matter. How much lift are you wanting in the rear? I would use shackles, AAL, and a small block if needed. Of course your best choice is lift leaf springs, but I am going to assume that's not an option.

 

I have the shackles already....and now looking in your sig you almost have the exact same setup I was planning on. What's your setup in the rear and how do you like it?

 

6" Softride Skyjacker Leaf Springs w/ Belltech 6400 Shackles (Shackles Set for 1.5” Lift)
2.0 Pro-Series 12" Travel .875 Shaft Fox Shocks w/ Reservoirs



I love it! Leaps and bounds better than stock.

 

I'm assuming you used FR36S for the leafs?

 

yeah, stay away from that big of a block, or stacked blocks

 

Correct, and they are on sale at Stylin Trucks for $422.28 with free shipping.

I would go with what KLC said as well. I did the blocks that came with the superlift kit, and I had soooo much axle wrap it was ridiculous...(sp?)
