Spring Time With Manley’s NexTek Lightweight Dual Drag Valve Springs

Valve springs could easily have the hardest job when it comes to parts that are attached the cylinder head of an engine. They are exposed to violent forces during the combustion process, and they must ensure the valves are able to do their job every time the engine turns over. To assist the valvetrain of drag racing engines, Manley designed their NexTek series of valve springs so they can deal with the harshness of drag racing while providing outstanding performance.

The demands drag racing put on an engine are extreme, to say the least; big compression, vigorous periods of wide open throttle, power adders, and more all can be a true torture test for components. Since Manley is in the business of developing valvetrain parts that can absorb heavy abuse, the NexTek valve springs were a natural progression for their product line. All facets of how and where the load is applied to the valve spring were examined to ensure the NexTek springs would perform as expected.

The NexTek springs are all about packing a lot of punch into a smaller product — that’s why they are significantly lighter than most springs. These springs incorporate a dual spring design that produces less heat and load loss because Manley reduced the amount of friction produced. This small design also allows the NexTek springs to provide a higher rpm range, while still maintaining proper valvetrain control. The NexTek springs are made of a special chrome silicon steel that possesses a high tensile strength that’s also free of many impurities to help with durability.

If you need to upgrade your valvetrain for peace of mind make sure to check out the NexTek springs from Manley on their website.
