Dear Welder Series…
I just purchased a 1950 Chevy 3100 truck where the seller installed WS21906 in the front and WS318500 in the rear of the original frame. I was hoping you could suggested an affordable set of coil overs that would work with this setup. Unfortunately I have no idea as to what I should be looking for in terms of the stroke, lengths, dampening, etc.. Thank you.
Congratulations on your new project! These are great looking trucks.
I suggest blocking the truck at ride height to establish coil-over ride height.
If the upper mounts for the front shocks have been installed, the ride height for the coil-overs will be the center-to-center distance between the mounting holes on the lower arms and the brackets. If the frame plates have not been installed, go to https://shared-assets.adobe.com/link/17afad9a-b219-4191-7cfb-7ee4bfa6277c?file=Coil%20Over%20Mustang%20II.pdf, pages 2 and 13 will help.
If the rear crossmember has been installed to mount the top of the coil-overs, the truck’s ride height you have chosen with the mock-up will give you the coil-over ride height. If there isn’t yet a place to mount the top of the coil-over, please consider the crossmember
The coil-over mounting angle is discussed at https://www.welderseries.com/tech/tech-sharing/coil-over-mounting-offset/ . The coil-over ride height can be determined when you mock up the crossmember and mounting points.
Regarding the coil-over stroke, generally longer is better as it will offer more suspension travel. Other factors or interference points also come into play. Viking, RideTech and other North American companies make quality coil-overs.
I hope this helps with your decisions.
Thank you so much!
