Lowering a 72 1/2 ton with leafs

[xs-cash]

Looking for a lowering kit for my 72 Cheyenne Super 10 , with rear leafs , I’m a old guy , not so internet hunting friendly , can’t seem to find much info , looking for a 4/6 or 5/7 kit , static height, any help would be appreciated. Thanx. Ps in Canada

There are 3 options for lowering the back of a leaf spring 67-72. First, longer shackle can get you an inch, maybe an inch and a half. New leaf springs can be purchased in 4 or 6 inch arch (maybe 2 as well) or a flip kit.

The flip kit on my 69 dropped the back just over 7” and I used ECE 2 1/2” disc conversion spindles and 2” springs in the front for a 4 1/2” front 7” rear drop.

I highly recommend 17” or 18” wheels so you can run more backspace. I switched to 5 lug wheels front and rear. The rear I did by swapping in a 71-72 wider axle housing to better accommodate my wheel/tire combo. Mine is a step side bed.

Then pick your poison with lowering options. Shackles, which I did on my ‘70 GMC C2500 Sierra Grande to get less rake and that worked great for that 3/4 ton truck.

If you want less than a 7” drop in the rear then you need to just suck it up and buy springs. IMO, 2” more drop in back than in front works good. So if you want to lower the back 4” with springs then do 2” in the front with springs or 2 1/2” spindles. 5” in the rear would work as well if you stagger your tire height.

I run 27” fronts and 29” rears on my 4 1/2”- 7” drop.

As far as I know,… DJM is the only company that makes flip kits for the 67-72 leaf spring trucks.
