Help...New Early Classic 4" drop springs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Estanley · 09-16-2002, 09:11 PM

I'm trying to put in my new springs and I'm not sure which end goes up or down. It has been a while since I took the old ones out. Here a picture please help!

Quick question???? Do you need to c notch your frame with 4" drops in the rear????????

Estanley · 09-16-2002, 09:24 PM

Not at all. EC says that 4" is on the boarder line when it comes to repositioning the rear shocks but I am going to try it without repositioning at first.

Dean23 · 09-16-2002, 09:25 PM

cool when the time comes I want to do a 2/3 or a 3/4 to my 68 not sure which yet

It shouldn't matter whitch end is up.. Both ends should be the same, because they require the same clamps. The front ones are the ones that have different ends. WES www.ClassicHeartbeat.com

I'm doing a 2/4 because they tell me that that's the max I can get away with on the front without drop spindles. 3" with just springs will cause negative camber (which means that the upper control arm runs up hill). This will cause the truck to have bump steer and act weird in hard corners.

Thanks WES now its off the computer and back to the garage to finish the rear suspension. I'll have pics later. THANKS AGAIN!!!!!!!!!!!!!!!!!

Estanley,
Do you have to buy shorter shocks for a 2/4 drop with springs?

**Classic Heartbeat** · 09-16-2002, 10:48 PM

You will probly be OK with the shocks that you have. What you will want to watch for is the angle of the shocks. The lower you go the greater the angle of your shocks. At some point you will want to relocate the brackets to bring them into a more stock possition for them to work correctly. My 67 panel has a 4-6" drop and the rear shocks are at too great an angle to be effective, so it is rather bouncy back there. WES www.ClassicHeartbeat.com

I've got a 4" drop with ECE's leaves on back (and their 2.5" drop spindle / disc conversion up front, all top-notch stuff if you ask me) and I'd say no, you don't need to c-notch it. It is borderline, though; I cut my bumpstops a bit to get just a bit more travel. I do think I'd probably benefit from it, but it's not so urgent that I'm gonna do it anytime soon; it's the kind of thing I'd do whenever I do a full restoration on this thing in 10 or 15 years or so, along with removing a few springs and bagging the rear to cut down on that leafspring bounce.
