Description

Chrysler Hemi 5.7L, 6.1L 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 are 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.
