1971 C20 Static drop.

Looking to drop my 71 c20 but i'm having a hard time finding the parts i need.. I DON'T WANT TO DO A C10 AXLE SWAP! I want to have a dropped 3/4 ton long bed for a bike hauler.

So far I found These for the spindles.

Springs


Can't find a flip kit for the rear! also don't know how legit the drop spindles or the springs are... ANY help would be rad!

Performance Online also carries C20 drop parts for the 67-72 trucks.

Re: 1971 C20 Static drop.

Are the rear leafs 2.25 or 2.5"?

Re: 1971 C20 Static drop.

POL sells the front spindles and cut one (or one and a half coils). 14bolt? They dont make flip kits for that. You need to buy new perches and weld them on.

Re: 1971 C20 Static drop.

Hate to bring up an old post but was wondering if spindles from a 1987 c3500 would work on a 1971 C20 suburban?

They are from early classics. It's the c20 to c10 conversion drop spindle. 2-1/2 drop. Check out there site but I believe it runs standard c10 brakes. Bought my truck with them on and when I went to swap to tubular control arms that's when I found out I have all 3/4 ton suspension. I ended up buying drop 1/2 ton spindles to run the tubular arms.

100 bucks plus the ride and there yours

The only thing I'm not sure is the brakes. I have 6 lug so that's why I thought I had 1/2 ton stuff up there. Not sure if you can run the 3/4 ton brakes
