Fitment Note

We identify many performance components by engine family rather than by every individual chassis. Verify the engine code, cylinder head/valvetrain configuration, and required supporting components before ordering, especially on engine swaps or modified vehicles.

Always verify installed height, coil-bind clearance, retainer-to-seal/guide clearance, and camshaft lift before final engine assembly.
