'72 GMC Suspension setup and vendors
OK.... so after looking around previous posts and asking a couple of questions myself, I think I know the setup I'm going to go with, but I want to double-check this setup and also get some info on vendors.
I have a '72 GMC w/leafs and I have decided to go with a 2.5/4" drop using the 4" drop leafs, 2.5 drop spindles and I'm guessing from what I have read that I should probably go with the shock relocators for the rear? So that brings up the questions... 1) Does this sound like a good setup to consider? 2) What about front shocks? I am assuming if I use a 2.5" drop spindle I will want shorter shocks? (I don't remember where the top mount is off the top of my head, so maybe this is a non-issue) 3) What vendors would you go with. I was thinking of Early Classic Enterprises since they are pretty close to home, but I've found the springs about $50 cheaper elsewhere. Are there any vendors you guys would avoid? Thanks for the help guys... I'll get this thing back on the road yet... Alan Elk Grove, CA |

I can help with the front shock question. The drop spindle doesn't change your suspension geometry at all. It just moves the wheel up on the suspension. The springs and shocks should stay at their stock height. You might want stiffer springs and shocks to offest the loss of travel though. I would suggest changing the springs at the same time as you do the spindle change because its a lot of work to get that far and not much more to swap the springs at the same time.
I'd suggest getting a GOOD set of spring compressors to get the front springs out. I lowered my 75 Olds Cutlass (same front end style) and had the cheap ones which doubled the time it took to install the new springs. You'll need shorter shocks in the back, but I'm not sure if you'll need to move the shock mounts for a leaf spring or only for a coil setup (I'll have to find out myself if I do this). I've ordered some parts from GMC Pauls and had good luck. They left out part of my gas tank order, but shipped it out the next day with no hassle. Also, they seem to have the best prices of anyone I've found. *edited poor english*

You can't go wrong with Early Classic, but there are some real good vendors on this site like GMC Pauls, Wes @ Classic Heartbeat, Mothertruckers, Tim Christianson (sp) etc. Check out the main page for the board.
Sounds like a good set up too.
