In March, 1966, Manley Speed Equipment, Inc. was founded by Hank Manley. Initially the line included stainless valves, forged pistons, camshafts, lifters, vanadium valve springs, push rods and timing chain kits. Known today as Manley Performance Inc., it continues to re-define itself in a high performance aftermarket industry that is constantly evolving. They’ve developed new products for growing markets such as sport compact, Ford Modular and Chevy LS, as well as maintained their leadership role with the traditional V8 engine business.

Description

These Manley NexTek valve springs are better designed 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.
