NexTek® Oval Track and Endurance Valve Springs
Manley's NexTek® valve springs are the latest in valve spring technology. The main benefit of the NexTek® springs is that they resist degradation of spring pressure in the later stages of a race. This is critical in oval track racing, where an engines valve train is abused for a long period of time. The spring inside diameter is chamfered for retainer clearance. The state-of-the-art winding process, thermal treatment and finishing practices cannot be duplicated, making these springs unique. The specially processed premium-grade chrome silicon is virtually free of impurities or surface irregularities, making for a high-quality, high-performance valve spring. NexTek® Series valve springs have been tested by leading engine builders and are confirmed to be the best performing valve springs on the market today!
