Good To Know

Q: Should retainers be replaced in sets? A: Replacing all retainers together during a valve job is good practice so wear stays even across the valvetrain. Confirm the correct part for your engine serial number before ordering.

Q: Does this fit both intake and exhaust valves? A: This retainer is listed for intake and exhaust valve positions on the 1503 platform. Always verify against your machine's parts diagram for your exact model year.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
