Default Mcgaupheys 3/5 to a 4/7 drop

Well,I would like to go a little lower with my truck.Right now Ive got the Mcgaupheys 3/5 drop,front is 2in spindles with 1in spring.Rear is flip with the block removed.Im guessing the front would be done with a 2in spring,but Im not sure how to get the rear lower.And Im guessing Im gonna need a cnotch.What do you guys think?

The only way to have a 5" drop in the back with a flip kit is by using the rear lift hangers. Replace those with stock hangers and you'll have a 7" drop. A c-notch isn't necessary. Most run helper bags to stiffen the rear up to keep it from bottoming out

or just run a stiffer shock and it'll only bottom out on hard bumps or if the bed is full.

I say notch it. I have a 4/7 on my truck and it bottoms out all the time. Well I say all the time but more than I would like it to.
