Calvert Mono springs-Tri-5 Chevy
These are a new design single mono spring designed for 1955 thru 1957 Chevy cars and wagons. These springs are made of a parabolic steel material to handle increased power levels, up to around 1200hp. They feature a standard eye front, and a reverse rear spring eye for strength and also enables us to offer several ride heights. These will bolt into the factory locations or into frame pocket kits, as they have the same 2" width as the factory sets.
