Rear Shock Relocation Kits

[67C10Step]

I am putting together a parts list for a total rear end rebuild on my truck. Most of the decisions are easy in that I am replacing all the brake hardware, shocks, springs, bushings, etc.

I am going to lower the rear 3-4" and leaning towards 4". I will relocate the rear shocks as well and have looked at the NoLimit and CPP kits. There is a large difference in price between these two kits and I am wondering what folks on here have used and their feedback.

Thanks in advance.
