Anyone with a half ton near OK that wants some 56 inch 1/2 Ton Heavy Duty OEM Springs RPO Code G50 Lemme Know I have them. I have 2 sets. They came off of an 80 and an 81 GMC. Neither truck was sagging. They're not only a bit heavier duty, but they offer better ride quality.

If you're half ton has the 52 inch springs, you'll need to move your rear spring hangers back 4 inches. Your frame should already be punched with the holes. You'll just have to drill the rivets then use Grade 8 bolts with thread locker to bolt them back on. I'm not sure if short bed trucks have the holes punched for 56 inch springs. I think short bed might be 52 inch spring only. $25 per pair.

If you really want to add some strength, I also have a set of C20 C6P 56 inch 3/4 ton springs too. You can expect some lift in rear end on a 1/2 ton.

Distance and shipping would probably kill a deal but if your close to OK or passing through OK we can make it happen.

I don't know the rating. I just know the RPO code was C6P. They appear to be 7+Zero Rate. Here they are just before I removed them from the truck.

Met with Al again tonight. :waytogo: Cool to get together talk trucks as usual. He bought a set of the C6P 3/4 ton springs. Still have both set of these 56 inch half ton springs.
