Suspension help

[53chevy]

Well, im getting into a project... Its a 1984 GMC 4 door long bed 1 ton, It has a dana 60 front and 14 bolt rear end. Im unsure of the lift is has. the front is 47" with 5 leafs and the arch has 9 1/2 " of arch ( off the truck) so im assuming it has 8" or 10" if lift. I think it may be a 8" front skyjacker due to the red bushings. The rear end is what im even more baffled about. It has 14 or 15 leafs... i dont have have it in front of me. It has an center eye to eye of 55". Any help of would be great

Fronts are 48" and rears are 56" and yes it sounds like 10" lift since most stock front springs are negative arch. The rear sounds like a stack of 2 sets of springs. Really need pics to be much more help, I'm wondering if it has rear shackle flip because that many springs I dont think would make up 10". You could also take a measurement from the center of the lock-in hub to the body crease, instead of the hood. Some of us here with stock trucks could take the same measurement and tell exactly what your lift nets.

So are the Red bushings a Skyjacker only trait? I've been trying to identify these lift springs I have, and they have red bushings. Look to be real nice tough bushings and they do look OEM to the sprigs.

I agree with C4. Some pics would help us help you a bunch. I'm updating your Model profile with a K, Also helpful since it's a 1 ton Crew Cab, is this a Single Rear Wheel (SRW) or Dual Rear Wheels (DRW)?

Thanks you, it is a single rear wheel. I'll try to get some pictures up today sometime. I'm going to get better measurements also.

 

[53chevy]

The rear springs are 26"x30" so it is a 56" rear spring that is 2.5" wide.

I'd love to have a SRW Crew Cab K30/K3500, but I really think I'm going to have to settle on all of my "wants" I want a K5 Blazer too, but I have a feeling I'll end up with a K20 Burb that might even start out as a K10 Burb and have to call it good. But, I do want 89-91. TBI and Mini Quads. Seems those later interiors hold up better too as far as the dash pads and door panels for some reason. I like that later fabric too, and Gray interior is a common color those years. I'm not so hot a interior and body work, even though I can do about anything mechanical.
