BLK6.0HD

Im running 315's on my 2500hd without a lift. I cranked up the t-bars and put a 2'' block in the back. I had to put the block in the back because i removed a couple springs out of the pack to get a beter ride. If i still had all the springs in the rear pack i wouldnt need the rear block. In the front i had to cut the corner of the bumper because it rubber alittle.

BLK6.0HD, which springs did you remove from the rear?
If these velvet ride shackles I bought don't do the trick I might try that next.

I pulled out the bottom overload, the one that 3/4'' thick and the 2nd spring down from the top. After removing these springs your going to need to get some new u-bolts. The stock ones dont have enough threads on them.

They will fit. But dont expect your ride to be "plush"....

I have 315's with stock wheels and a 3 inch body lift no problem. I had to trim the corner on the bumper but thats about it. I barely ever rub (only when being stupid offroad) and thank the tires kick *** and look good too.

If you have 4.10's you will be ok. But if you have 3.73's you will notice a pretty bad decrease in power off the line.

I lost a little bit of towing power going from bald street 285's to 315 MTR's, but I think it was worth what little bit I did loose. After my nelson tune gets here I think the difference will be a lot harder to see. One positive thing is that I didn't really loose any mpg on the highway. I do think I am a little slower though right off the start, but not terrible.
