Manley Performance offers this NexTek Series valve spring set, part number 221420-16, for builders focused on Super Stock and Competition Eliminator classes. These springs are engineered to handle the demands of high-performance camshafts and aggressive engine operation, ensuring reliable valve control under extreme conditions. If you're assembling a serious competition engine, getting the valve springs right is critical for both power and durability.

The NexTek Series springs feature a 1.500 inch outer diameter and are designed for a .850 inch lift.

This consistency is key to extracting maximum performance and protecting your engine.

This set includes 16 springs, enough for a standard V8 engine. When undertaking a build of this caliber, it's important to ensure all valvetrain components are compatible and installed according to manufacturer specifications. Proper installation is key to achieving the performance and reliability these springs are designed for.
