Manley Valve Spring, SPRING-1.677 TRIPLE - 221449-16

From drag strips to short track and endurance circuits, the Manley NexTek® series is engineered for serious racers. NexTek® springs resist pressure loss and valve-train degradation even in the most demanding race conditions. That means more consistent spring force deep into a run, reduced valve bounce, and improved overall stability for high-RPM performance. Built to outperform and outlast in real-world competition.

Features

• Specially processed premium-grade chrome silicon that is virtually free of impurities or surface irregularities
• Better valve train stability and component life
• Ideally suited for Sportsman Drag Racing applications
• Available in polished versions to reduce friction, improve fatigue life, and minimize load loss
