Manley NexTek valve springs, 1.677 in diameter and .800 in lift (set of 16), are built for demanding race use where consistent spring force is required. The NexTek series resists pressure loss and valve-train degradation to reduce valve bounce and improve stability at high RPM. Manufactured from specially processed chrome-silicon material, these springs are offered to suit sportsman-level drag and circuit racing environments.
