Supertech Titanium Retainer for Spring SPR-M1007D 6.5mm Stem

Supertech is known for making well-built engine components, and this titanium valve spring retainer is a great example of their focus on performance and durability. If you're working on an engine build where valve train stability is key, this retainer is designed to help. It's made from titanium, which is significantly lighter than steel retainers, reducing the overall mass that the valve spring has to control.

This lighter weight means the valve train can handle higher RPMs more reliably because there's less inertia for the spring to overcome. It's specifically made to work with Supertech's SPR-M1007D valve springs and fits 6.5mm valve stems. When you're building an engine that needs to perform at its best, every component matters, and using lightweight, strong parts like this titanium retainer can make a notable difference in how smoothly the engine runs at high speeds.
