Product Description
OEM: Factory set of BMW retainers.
CHROMOLY: High-strength Chromoly steel valve spring retainers. While not as light-weight as the titanium, these are perfect (higher strength and durability over OEM) for a street-performance/hotrod engine build. Made in the USA. These only fit the OEM style dual springs. This is for a complete set of 12 retainers. (Currently Out of Stock)
TITANIUM: Plenty strong, yet are much lighter than stock steel units – this helps reduce reciprocating weight in high-revving engines. These should be considered a wear item and a RACE ONLY part.
