Going to lower my single cab nnbs and want to know what the lowest I could go without having to c-notch the rear (I'm going to remove the bump stop and mount it directly into the frame). I have some parts to drop it like the spindles for the front, and I have shackles and drop hangers already. Any positive input is welcome

Why not just notch? Your cutting on the frame already with removing the bumpstop.

Well not really it's just the welding around the frame I'm cutting to remove the bump stop. I'm just more nervous of messing with the frame ya know lol

4/7, will hit the frame on bad bumps at high speeds but otherwise you're good to go.

It's not a big deal really. The notch is heavier grade steel than what the frame is. I bolted mine in but will have it welded at a later date. But I can understand not wanting to cut. I'm considering the weld-in underbed notch. Much much stronger.

I might consider that later on then once I go lower. You should send me some pictures of all that how it is now and once it gets welded

It depends on what you can deal with... For me, I wanted my stock ride back after lowering the rear and not having a notch was not an option, especially for the girl... Drop it first, see if you can handle it without the notch, then notch it later if you have to. You don't have to do it right away. I dropped mine 10" without a notch, needless to say it didn't actually drop 10" because it was laying on the frame and it was the worst ride ever. I brought it up to 7" drop and notched the frame. I couldn't be happier.

My '13 RC is lowered 7 inches with factory bump stops brackets removed and McGaughys conical foam bump stops screwed into the axle frame pads. Rides fine. There is clearance (about one inch) between the top of the bump stops and the frame. G-load compression is very "cushy" with no hopping. If I was to use my truck as a "real" truck, then I would install the McGaughys airbags. Just did not want to cut up the frame on my new truck. Having said that, I've notched several NBS trucks with excellent results.

FWIW, with 6500 miles on the truck, McGaughys 4/7 drop kit (with struts and shocks) is holding up well and the ride is fantastic! No bump steer or rear hop. Good luck!
