Material and Design

Brian Crower's application information describes these performance keepers as precision-machined from billet chromoly steel and heat-treated for strength. The 1JZGTE catalog identifies a 6mm valve-stem application and compatibility with matching BC and OEM retainers. Verify the actual valve and retainer specifications rather than treating that catalog designation as a universal fit guarantee.

What Is Included?

One BC2950 set containing 48 keeper pieces. This is not a valve spring, valve or retainer kit; those components are selected separately. The package quantity is one keeper set, not one individual keeper.

Installation Considerations

Have a qualified engine builder verify full keeper engagement in the valve groove, correct retainer seating, installed spring height and relevant valvetrain clearances. Do not mix incompatible keeper angles or groove profiles. Inspect mating parts for damage or wear and follow the applicable cylinder-head assembly procedure.

No vehicle-year coverage, maximum engine speed or horsepower rating is implied. Compatibility depends on the cylinder head and valvetrain components actually installed, including on swapped or modified engines.
