LS LS1 660" Dual Valve Spring Retainers For 4.8 5.3 6.0 LSX LS2 LS3 LQ4 LQ9 LS

Dual Valve Spring Retainers for GM LS

These dual valve spring retainers secure valve springs on high performance engines to prevent valve float at high RPM levels.

Overview

These dual valve spring retainers for GM LS are designed to handle the increased stress of high-lift camshaft modifications on popular V8 engines. Engine builders rely on high quality dual valve spring retainers for GM LS to maintain stable valvetrain operation under demanding track or street conditions. The lightweight construction of these dual valve spring retainers for GM LS minimizes valvetrain mass for faster throttle response.

Specs At A Glance

Good To Know

Q: Can these retainers be used with single valve springs? A: No, these are engineered specifically with step steps to locate and secure dual spring configurations.

Q: What material are these retainers made from? A: These are typically machined from high tensile steel or titanium to handle heavy duty valve spring pressures.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
