planning on dropping the truck but cant decide how to go about the back. last time i went 4-7 on my 08 rcsb, but on my ccsb i either want to go 3-5 or 3-6.

on front i plan on doing spindles and belltech struts, but how should i go about the rear.

plan on running 285/40-22's up front ad 305/40-22's on back.

still want a good comfortable ride and looking for something that will be the best when it comes to traction when i start modding the new 6.2

 

I'm doing the exact same thing in my CC.
Front spindles and belltech adjustable shocks.
My plan for the rear is, I ordered a DJM 6 inch flip kit and the I have ground force 1-2 inch drop shackles which when reversed should make the kit adjustable to a 4 or 5 inch drop.
I also order shortened rear shocks.

 

Let me know how the different size tires work. The ABS may not like the size difference. I'm running 285/50-20's all the way around right now. I want to run 295/50-20's in the rear and 285/50-20's on the front but don't know if the computer will allow it.

 

you'll be fine up to about 1-1.25" of difference. my 08 had diff. size tires on front and rear and i had no problem when it was about a 1.25" difference

the only tiem i had trouble was when i was running 285/35's up front and 305/40's on back. which was 1.7".... i only happened like once a month or so, the abs light would come one and the brakes worked fine but abs was de-activated. all i had to do was turno it off for 5 min or so and it was fine

 

Thanks mikeith, I knew it would allow some difference, but didn't know how much.

 

for front i would do
2" spindles and coil relocator(cheaper than belltech struts)

rear
you don't have much of a choice but to do flip w/ hangers
or
flip and air shocks, and just air up to provide the lift.
or
leaf springs, hard to find, expensive, reduce payload


but luckly i found you some

not sure if you really want to run that size tire, you will have some gap if you do 3/5

this is mine with 275/45/22 on 22x10 wheels on a 4/7

 

wow I think you sold me on a 4/7 thats a beautiful truck...also where would I find the coil relocator?
