One of the most popular modern upgrades for the classic C10 is ditching the original A-arm and coil spring setup in favor of a full coilover conversion. This gives you adjustable ride height, corner-specific tuning, and significantly improved handling.
This thread discusses factory-style drop spindle approaches vs full aftermarket subframe swaps, coilover spring rates for street use, and what alignment changes to expect. We also cover what budget range to expect for DIY vs full kit installs.
For those who want to lower their classic truck without going full coilover, the Pomya Suspension Lowering Kit for 1963-1972 C10 is a solid dropped springs + shocks kit that delivers 3" front and 4" rear drop.
What suspension direction are you going on your classic build?
