Manley 261424 - Big Block Bracket Super Gas / Super Comp. Valve Spring and Retainer Kit (.880in max lift)

Manley Valve Spring Kit, KIT-NexTek SPRING

Double Spring w/out Damper: 221424-16 (149 g) - 10° Ti Retainer No. 23640-16 (20 g)

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.

  • Squeeze more RPM out of your engine and avoid valve float
  • Special heat treated titanium for maximum strength
  • Lightweight retainer does not sacrifice reliability
  • Advertised pressures are achieved after springs have been pressed solid three times
