Made from 5160 CrSi premium wire, our springs feature a linear 530 lb/in rate for improved handling and decreased body roll.
The 4050F springs are stiffer than stock, perfect for performance applications like Auto-x and Pro-Tour. Our springs are engineered for a 2” lowering with standard SBC, aluminum head and intake Big Block, Pontiac 400, and LS power applications.
They are also suitable for full weight Big Block setups when a ¼” nose-down rake is desired. With a tough black powder coat finish, these springs are built to last and proudly manufactured in the USA.
With consistent rates and only the best materials, our springs ensure your car sits properly for years to come. The linear spring rates provide a firm yet comfortable ride, eliminating that floating feeling on the road.
Suitable for a range of applications, including Pro-Tour, Auto-x, and general cruising, our premium springs are the best in the business.
