How do ya drop the rear of a C20 with leafs 2"?
Sorry for the barrage of questions!
I know there's lots of threads about this, but I couldn't find this specific answer. I've got a '72 C20 with leaf rear suspension (HD option?) Anyway, I want to leave the ride height stock for now, 'cept I'd like to drop the rear 2" to level it out. How's this done? Are there 2" longer shackles available? If so, where? It appears that 2" longer shackles might not quite fit under the bed, but I'm not sure. It's a fleetside metal bed, BTW. |

Not sure on a C/20. I just got Early Classics catalog today and they only offer leafsprings (with drop) for C/10's. I don't remember seeing anything for the 3/4 tons from any vendors. Doug

Check the catalogs or contact one of the Board vendors like GMCPauls or any of the others. They are all good companies with good employees.
How wide are your leaf springs? What is the length (bushing to bushing) of your leaf springs. My leafs are 2.25" wide adn approx. 51+" long (bushing center to bushing center).

I'm lookin at raising the front. Still playing with these http://www.classicperform.com/Store/...k/6372SHKR.htm
Tomatocity and I have talked about it before. Spring dimensions will be important to make sure the shackle will fit. Talk to tech support of whatever company you choose. |

For such a minor drop,possibly rearching the springs may be the best route.you will still have the load capacity, & no issues with longer shackles/box floor clearance. best of luck, 69L

Rich these are drop shackles and they would lower your truck. I think we should slam your truck and leave the same wheels and tires on it

That would be "dearching" Longhorn
Any local spring shop will pull the pack and flatten them out 2" usually under $100.00.

Didn't know that was a common thing. Thought it was a "lost art". I love this place. Thanks for the thread and info.

Thanks for the info!
Thanks for the info guys. I was hoping to hear that a longer shackle was available (or somethin gsimilar), but maybe it's not. I've searched all over, but haven't found anything.
I may end up rearching the springs, but I'd prefer not to. |

Dumb question, but is you axle spring under or spring over? Not knowing much about somethings maes me have to ask. If it was sprung under, you could put a block in there lowering it more??!?!

Ray's Fort Worth Champion Spring. Have them dearched to whatever ride height you want. You'll maintain the mechanical integrity of the spring pack (load capacity, spring rate, etc.), which will be altered substantially if you start pulling leaves out of the spring pack.

Shackles are okay.

Actually, they hang DOWN to the springs, so longer ones WILL work. |

Let the air out of the rear tires until you achieve the 2 inches.
Not sure how yours is set up but mine has overloads on it and by simply taking out the overload springs and the spacer and then using new u bolts I could acheive 2-3 inch drop on the rear of my truck.

Hmmm...

I've got the overload springs too, but that's only about 1/2"-3/4" of thickness. I'm not sure what spacer you're referring to. |

I took my truck to a spring shop and they removed the leaves and individually de arched each one. I do not know how much it changed the amount of a load I can haul.
