Supertech Titanium Retainer for SPR-TS1015 Mitsubishi Evo X 5.5mm Stem 7 Degree

This is a Supertech Titanium Retainer, specifically designed for the SPR-TS1015 valve springs and compatible with 5.5mm stems on a 7-degree lock setup. If you're working on the valvetrain of your Mitsubishi Evo X, this retainer is a key component for ensuring proper valve spring function and durability. Titanium construction offers a good balance of strength and light weight, which can be beneficial in high-RPM engine applications.

Choosing titanium for your retainers means you're opting for a material that's strong enough to handle the forces exerted by the valve springs, while also being lighter than steel. This reduced mass can help improve valve control at higher engine speeds. This particular retainer is made to work with Supertech's SPR-TS1015 springs, so make sure you're matching it up correctly for optimal performance and reliability in your Evo X's engine.
