how low can you go with drum brakes?
Just woundering cause i have drums on all four corners of my 69 c10 2wd. I want to lower it as much as I can and still be able to get it aligned properly. A couple of company's have told me that 2inches is as low as I can go with drum brakes. I will need to switch to discs if I want lower.

A 3/5 will work and I will still be able to correct the caster and camber to spec?

Re: how low can you go with drum brakes?
You can notch and z the frame, body drop, and lay rocker with drum brakes....
I had a 4-6 drop with drums with just springs, no problems with alignment. Posted via Mobile Device

Re: how low can you go with drum brakes?
Would just a 3/5 drop require control arms or could we just get by with springs and shorter shocks?

Re: how low can you go with drum brakes?
mine is about 5" down. Still have the drums right now. Alignment was fine. Bumpstops removed but it bottoms out over small bumps. Would need to shave the metal stop mounts off the lower control arms to keep it this way and be able to have any suspension travel. Tie rod ends are at some pretty nasty angles also and they would probably bind up going over bumps. There is no way you can go lower than this without drop spindles or doing some heims joint tie rod ends and longer camber bolts at least. I have CPP disc brakes and drop spindles to install in the springtime as well as air bags so Im not keeping it lowered this way. I would say 4" is max you want to go down with just drop/cut springs. That way you will still have an inch or two of usable suspension travel. I would say cut 2 coils off your front springs and order some 6" drop springs for the rear. You might have to get shorter shocks for the rear. Hint: Put a set of front shocks in the rear to use as drop shocks. They are the perfect length.
This pic is with a 15x8 rim and a 215/70R15 tire and stock front shocks. You dont need shorter front shocks unless you are bagging the front and trying to lay your control arms on the ground. My shocks arnt bottoming out even with 5" drop in front. Dont buy shorter shocks unless you need them.
