Michigan Motorsports SR007-16 - Valve Spring Retainers — Overview
This is a set of titanium retainers with valve locks for LS and LT beehive valve spring setups. It is not a BMW-specific part, so there is no direct F30, G20, E92, or B48/N55/S55 fitment to call out here. If you are swapping a GM V8 into a BMW chassis or building a track car with LS or LT power, this is the kind of valvetrain hardware you match to the spring and installed height you are already running.
I would pick these when you need a lightweight retainer for a beehive spring package and you already know your spring, lock, and valve compatibility. Titanium makes sense in higher-rpm builds where valvetrain control matters, but it is not something you buy blindly just because it sounds better than steel. Measure installed height, verify lock angle, and confirm retainer-to-seal clearance before final assembly, especially on mixed-brand spring kits.
