Re: Dad's 1979 GMC Heavy Half Transformation
Finally put the rear end together. Swapped the 3.08 for 3.73. Removed the overload and one leaf on the HD springs in order to gain another inch of drop. It's finally rolling on an extra set of rallies and scab tires. Don't mind all the footprints on the frame, the kid was enjoying bouncing on the rear.
OK, so I go to the front of the frame, climb up on the frame and give it a bounce.........nothing happens? The only bounce I get is from the under inflated tires???? I know there should be at least a little give in the springs, but nothing, nothing at all!! Today I call the local spring company "Husky Springs" to ask a few questions. Yes, I understand that it's just a bare frame minus engine etc. Anyway, after taking some measurements, we determined that the springs I put in are rated at 1060 pounds each, verses the second coils springs they sell rated at 843 pounds!!!!! I guess my 170 pound body isn't going to put a bounce into these springs! Still, even 843 pounds springs seem excessive?
Needs thoughts from the experts. The springs are standard height. Thanks Mike
