New Resr Springs Too Wide for Hanger - The 1947 - Present Chevrolet & GMC Truck Message Board Network

RussG · 03-01-2017, 03:22 PM

I have a 1949 3100 and recently purchased new rear lowering springs. I tried to install them but the spring is too wide for the hanger. The old spring measures about 1.69" the new one is 1.72-1.74". Has anyone had this same problem and what was done to fix it? Thanks Russ

It was always my understanding that stock springs were 1.750 or 1-3/4 inches.

I think on the front of my truck I had to take a bit off the inside of the hanger or "smooth it out' when I put it together because the hangers were slightly collapsed due to possible over tightening at some time.

On yours it shouldn't take much work with a flat file, flap wheel or grinder to take a couple thousandths off to get it to clear. Even with the bolt/pin tight in the hanger the spring should swing up and down on the bolt easily as you don't want it to bind up.

I agree: hit the mounting eyes with a sanding disc on an angle grinder, cover it with some fresh paint, and you're done.
