One Ton Leaf Springs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok, so it's pretty common knowledge that you just about need a KIDNEY BELT to drive a 67-72 one-ton leaf spring truck with no weight in the bed.

For whatever lame reason, I don't want to take the "1-ton" out of the 1 ton. I want to keep it what it was/is. But if I could save my organs from a little abuse, I'm all for it.

I know some of the newer trucks have like 3 stages to the springs; primary pack (1-2 leaves), secondary (3-4?), then an overload spring or 2. Has anybody upgraded to a more modern leaf and experienced an improvement in the empty ride quality?

On that same note, does anybody know who carries replacement leaf springs for these things? The only leaf's I've come across are for 1/2 ton's.

A spring shop can build you new leaf packs.The newer springs are longer.You can use those by moving ypur sprimg hangers on the frame.it`s done ll the time on 4wds to gain more flex.

Thanks! I'll have to look into that. Of course, a few bags of sand in the bed would accomplish the same thing... and wouldn't hurt the mileage (what mileage?).

That`s all true.

what i found on my first one ton was that it had only about five main leaves(it was a long time ago) and had another leaf pack on top of it of about another 6 or 8 that contacted the factory overload perches on the frame. you probably will need a spring shop to make this for you, or you could find some out of a 3/4 ton and cut the eyelets out. hope this helps
