Coil-Over set up for 67 C-10 with big block and Mustang II suspension - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What spring rates do I need for a 1967 C-10 step-side with a 396 automatic and a Mustang II front suspension? I have QA1 coil overs in the rear with a 300lb spring and someone said that will be too stiff. I do not have the coil overs in the front set up yet.

I went with 650 lb front springs on my '67 step side, but I'm running an all-aluminum LS1.
Call QA1 and talk to them, they have excellent customer service, and helped me decide on the correct ones for my build.
