Leaf Spring Conversion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was wondering if anyone knew if it is possible to put front leaf springs off of a 73-87 4x4 on a 67-72 4x4. I realize that they are turned different dirrections, but I need to make my front end a little higher. I put a ranch hand style bumper on my 72 K20 and I'm not sure if the 42 year old springs will last very long. The old beast dropped a little after I got the bumper mounted up.

I don't know about swapping in the later springs but you can always add another leaf to your existing pack

I'll have to look at my spring pack for that. How hard is it to do?

Would I be correct in saying that since my 3/4 ton only has two leaf front springs someone has most likely put in half ton springs?

Ok I got it now. I think I'll make a trip down to LMC in Kansas City snd get me some 3 leaf springs. Since I need new front springs I may as well go heavy duty or go home. Thanks for y'all's help
