# Manley GM LS Series Super Finished H.P. Valve Springs .650 Max Lift (16 Pieces)

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.

-   Manufactured from “super clean” Hi-Tensile Chrome Silicon steel
-   Proprietary multi-step heat treating minimizes load loss
