How to tell how much drop coil springs have? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Todd68Chevy** · 03-01-2011, 09:12 PM

I have a pair of front and a pair of rear coil springs but I do not know what drop they are. Is there anywhere that shows with the over all height of the coil what they are? I got both pairs with other parts and would like to verify what they are. The front pair measure approx. 10 1/2 inches and the rear pair are approx. 11 inches. Thanks for any information and help.

I'm Thinking if you call ECE Tech Support, they might be able to help you. Here's their Web Link:

Thanks for the information. I will try calling them. I am not sure what brand they are and did not know if the companies would help. Todd

I would be careful trying to determine what they are,... if you don't know who manufactured them.
Spring rates and uninstalled heights will vary from brand to brand.

That is why I am trying to find out something about them. I Will not sell them if I can not find out anything. Is there anyway to find out the manufacture? I meant to ask that in the first post and forgot to include it. Thanks Lolife99

Short of installing them,... I see no way to tell.

Different spring manufactures have different spring rates for the same size drop. So a spring could have the same installed drop as a different spring but different height, coil size.

Thanks for the information. I just thought there might be something that would show what brand they could be and drop amount. Thanks for your time and information. Todd
