do u have to C-notch the frame on a 72 GMC sierra (1/2 ton) if u wanna lower it 4/6....i was talking to a guy today and he said he had no choice but to to it to his (2002) pickup because he kept bottoming out
please let me know, cause i wasnt planning on cutting my frame, i did it once to a 98' S-10 (c notched the frame and did an airbag setup with a 4-link...it was a pain

thanks again
Kevin

If it's a coil spring truck, no, you don't.

The later model trucks like your buddy'd do need a notch for a 6 inch rear drop though.

ive got the coils in the front, but ive got leafs in teh rear. (early classics sells the 4" lowering leaf spring setup and then the 2" shakle.....also will i also need a shock relocater kit aswell?

Definitely call ECE and ask them. Those guys will steer you straight. They get the Tx Firefighter Stamp of Approval (TFFSOA, TM, patent pending).

Don't use a 2" drop shackle if you have a wood floor. That would be a huge pain. It will hit the wood floor. ECE sell's a 1.5 " shackle that's what you will need.

Here's mine and a pic of the notch I have. Maybe this will give you an idea.

thanks everyone...i dont have a wood bed (nor do i plan on getting one...so that shouldnt be a problem). so for a final answer, if i get teh 4"lowering leaf springs and the 1.5" lowering shackels....will i need to notch the frame? (cause i really dont want to, nor will i) and i need to know if i can lower it 4/6 with out any problems

Thanks Again
Kevin
