Supertech Retainer 5.5mm Stem Spring M1007 TS1015 Titanium

This is a Supertech titanium spring retainer, designed for 5.5mm valve stems and compatible with M1007 and TS1015 spring sets. Retainers are a critical part of the valvetrain, working with valve springs to keep the valves seated properly during engine operation. This particular retainer is made from titanium, a strong and lightweight material often chosen for performance engine builds where reducing reciprocating mass is important.

Using titanium for retainers helps lower the overall weight of the valvetrain components. This can lead to improved engine response and allow the valvetrain to handle higher RPMs more reliably. The M1007 and TS1015 spring compatibility means it's intended to work with specific spring kits, ensuring proper fit and function when used together. This part is a good choice if you're rebuilding or modifying an engine and need to replace or upgrade your valve spring retainers.
