About this part

Product Details

These Manley valve spring retainers are made from 6AL-4V titanium, a strong and lightweight material chosen to help reduce the overall mass in your valvetrain. This reduction in weight is important because it allows your engine to achieve higher RPMs more reliably. They are CNC machined to very precise measurements, ensuring they work correctly with your valve springs and locks. You'll need to use 7-degree valve locks, and Manley recommends their P/N 13098 or factory Chevrolet LS valve locks for this application.

The design of these retainers is focused on maximizing strength while minimizing weight, which is crucial for engines that see a lot of use or are pushed hard. The specific titanium alloy and machining process contribute to their durability and ability to handle the stresses of high-performance engine operation. They are designed to fit valves with an 8mm stem diameter and have a .935-inch outer diameter, with an installed height of +.050 inches.
