Manley Small Block Chevy LS Series .600in Lift Single NexTek High Perf Valve Springs

SBC LS-Series, LT1 & Early Model LT-1 / LT-4 / L-98 NexTek® Series High Performance Hydraulic Roller Valve Springs - Set of 16 by Manley Performance. These Manley NexTek valve springs are better-designed valve springs using state-of-the-art machinery for purpose-built racing engines. They're manufactured from super-clean, high-tensile chrome silicon steel and are shot-peened to MIL specs for maximum fatigue life. They feature a proprietary, multi-step heat-treating that minimizes load loss and have computer-aided modeling to minimize valve bounce and valve gear separation. The Manley NexTek valve springs are smaller diameter and lightweight, allowing engines to rev higher faster. They have an extended tip thickness designed to eliminate overload breakage, and their tightly controlled open-end flatness reduces valve stem side loading.
