Speedmaster 200 lbs./in. Spring Rate 12" Tall Coil Over Shock Springs - Black Pair

The Speedmaster 200 lbs./in. Spring Rate Coil Over Shock Springs are a matched pair of high-performance suspension components designed for custom vehicles and performance applications. These 12" tall coil over shock springs feature a 200 lbs./in. spring rate, delivering controlled compression and rebound to support modified chassis setups. The black powder-coated finish provides durability and corrosion resistance.

Coil over shock springs are essential for lowering kits, custom suspensions, and race vehicle builds where precise ride height and handling characteristics are critical. The 200 lbs./in. rate suits mid-sized vehicles and moderate performance demands. As a pair, these springs ensure balanced front or rear suspension geometry. Compatible with most coil over shock assemblies, they replace worn or stock springs when upgrading or rebuilding suspension systems. The robust construction supports both street and track applications.
