Manley Drag Race NexTek Series 1.677in Dia .900in lift High Performance Valve Springs (Set of 16)

What you get in this box is a set of sixteen Manley Drag Race NexTek Series valve springs. These are specifically designed for high-performance applications where extreme lift and rapid valve events are common, like drag racing. They feature a 1.677-inch outer diameter and are built to handle up to a .900-inch lift camshaft.

Manley has a solid reputation for making well-built internal engine components, and these NexTek springs are no exception. They use a high-tensile wire that’s been stress-relieved to ensure consistent performance and durability under the intense pressure of racing. The NexTek design is an updated approach to spring technology, aiming for improved stability at high RPMs and reduced spring surge. This means the valves will follow the camshaft profile more accurately, which is crucial for making power and preventing valve float when you’re pushing the engine hard.

When you’re building a serious drag racing engine, the valve springs are a critical component. They need to be strong enough to close the valves quickly and reliably, even with aggressive camshaft profiles and high engine speeds. These Manley springs are engineered to meet those demands, providing the necessary support for high-lift cams and ensuring your engine’s valvetrain stays synchronized during extreme use. Make sure to consult your engine builder or Manley's technical documentation for specific installation requirements and compatibility with your cylinder heads and camshaft.
