About this part

Product Details

If you're rebuilding the top end of your LS engine and pushing the RPMs, you'll want to pay close attention to your valvetrain. These Manley Titanium Valve Spring Retainers are a smart choice for reducing rotating mass. By using a special 6AL-4V titanium alloy, Manley has managed to make these retainers incredibly strong while also being very light, weighing in at just 11.0 grams each. This reduction in weight helps your valvetrain spin up faster and allows for better control at higher engine speeds.

These retainers are CAD designed and CNC machined to ensure they fit precisely and perform reliably. They are specifically designed to work with 7-degree valve locks and are intended for use with 8mm valve stems. For installation, you'll need to use either Manley's P/N 13098 valve locks or the factory Chevrolet LS valve locks. The installed height is set at +.050 inches, which is a common setup for many performance LS builds.
