Supertech Titanium Retainer 6mm Valve Stem SPR-TS1015 M1007D

In this package, you get one Supertech titanium retainer designed for 6mm valve stems. These retainers are a popular choice when rebuilding or upgrading a cylinder head, especially for applications where reducing rotating mass is a priority. Titanium is significantly lighter than steel, which helps the valve train respond more quickly and can allow for higher engine speeds.

Supertech uses titanium for these retainers because it offers a great strength-to-weight ratio. This means they are strong enough to handle the forces from the valve springs but are also very light. This reduction in weight at the top of the valve stem helps reduce the overall inertia of the valve train. This can lead to improved valve control, especially at higher RPMs, and can help prevent valve float. The retainer itself is well-made and designed to fit securely onto the valve stem and work with compatible valve springs.
