These exlusive, USA-made progressive rate coil springs compress under load after braking or cornering and gradually become firmer. The 100 percent load tested springs feature hot wind from SAE516H, oil quench, temper, water quench, shot peen and ground flat.
Please Note: Mustangs manufactured in 1970 with a 351C engine can choose either Small Block or Big Block springs based on the vehicle’s options. 1970 Mustangs with a 351C engine with heavy, factory, cast-iron intake; power steering or air conditioning might be better suited with the Big Block version but can choose the Small Block version as well. On all other 351C engine applications, the Small Block version is recommended as the car may sit higher than preferred if there is not enough weight over the springs.
