Stock 1/2 ton front coils - The 1947 - Present Chevrolet & GMC Truck Message Board Network

OhOneWS6 · 03-26-2010, 05:11 PM

Anyone have any stock front coils they took out of a 71 or 72 1/2 ton, small block truck they could measure for me. Pics would be a big help as well. I'm trying to figure out if these are the original stock springs out of my truck. Speculation is they may be 3/4 ton or 73 & ^.

Side by side with ECE 2" drop springs

If I remember right, I was told that stock springs measured 13 inches. Those also look a little beefier so maybe your theory is correct.

My Stock springs measure 14" top to bottom (after removing them from the truck). I have a 72 1/2 Ton, 350/350

Oh, and the stock Delco springs I bought to replace them, measured 13.75" top to bottom.

That sounds reasonable close to mine. I could see them being 1/2" different after 40 yrs of settling. Anyone else?

I just pulled a 72 front end apart today, the ones out of it measure a little shy of 13 3/4

That seems reasonable close as well.

I guess the next step is to measure the diameter of the wire used to make the springs. Anyone got a set of calipers they can check that with?

Keep them coming. I need as much info as I can get. Here is the issue we (ECE and I) are tying to resolve.

No one with stock springs and a dial caliper??? Mine measured .776

BOZO · 03-27-2010, 09:42 PM

My stock 1969 1/2 ton small block front springs measure .778.

Thanks BOZO. That is pretty close to mine. It seems my springs are no different than any other 1/2 small block springs as far as the dimensions. I guess they could still have a different rate if the material is a different hardness.

Anyone else got a set of stock 1/2 ton springs laying around? More information is always helpful.

Mine looked almost exactly the same when I took them out side by side with the 2" drops (if you recall from the other thread). I measured the drop springs before putting them back in, they were 12" exactly. The stocks I don't have a pic of, but they were (cut two coils) just over 13", but that's on a 38 year old Georgia farm/ranch truck with a quarter million miles. spindle center to fender measurement was just over an inch less with the drops installed.

My springs are 12 7/8 " high. I don't have a set of calipers. The spring diameter is 5 1/2 ".

If you go to NAPA's web site the give the hight and coil thicknes of there springs.

OhOneWS6 · 03-29-2010, 11:11 PM

Thanks Frank.

1-PU I am only concerned with factory original springs. I'm trying to figure out another issue.
