Its been awhile since Ive been in GM. Im not sure what I need, but I know the stance Im after.

2009 GMC Sierra 1500 Extended Cab

The stances Im after:

Im not looking to notch at all. I want little fender gap.
Debating on 24's or 22's. Im thinking/afraid if I go 24's, Ill have to get rubberbands to wrap the wheels in and Im not wanting to do that. The roads here arent the greatest and blowouts on tires with virtually no sidewall might spell disaster.

If you dont want to notch the rear then a 4,5/7 is a good drop.

Im thinking 4/6 or 4/7

I just want it low and level. Last time I had a NNBS Regular Cab and there was a 1/2" rake

The 4/6 it is as the rcsb 4/7s have been known to have a rearward rake but mine sits level so.....i did play with the spacers on the belltech struts to get mine level because at belltechs specs my 4/7 was more like a 6/7 lol.

What do you guys think about that inexpensive 2/4 Rough Country kit? Doesn't seem to be too many comments about it in here. Are you still able to add on a rear sway bar with a simple 2/4-4/6 drop on a rcsb 2wd? I just got back into a nnbs after a few years, but all I had on my old Silverado were drop coils and shackles in the rear. I'm hell bent on making sure this new truck has a sway bar, so any info would help out.

Only if you want to go really low, like 7in or more in the rear.

You will need to remove the factory bump stop mount from the frame to gain you 2-3in back after the flip kit, otherwise the axle is going to sit super close to the bump stop. I think most flip kits tell you to do this anyway.

No matter what you do, when lowering a nnbs do yourself a favor and invest in GOOD shocks. Viking/ride tech/ etc, what ever you have to do to make them work will be worth the time and effort. I had my nnbs crew cab at 4/7 with McGaughy(sp) shocks up front and air shocks out back and it was AWFUL. I lifted the truck up to a 2/4 (obvious the height helped) but added Fox shocks and now I regret not staying with the 4/7 with better shocks. I also have the 14bolt rear axle which is a beast, and the pumpkin would bottom out on the bed floor at a 7'' drop. Just some friendly advice.
