Mechanic's Note: To ensure fitment, measure the outer diameter of the locking tabs on your current cap. If it measures approximately 35mm, this is the correct replacement. We recommend applying a small drop of Lock Lubricant (Graphite) to the keyhole once every few months to keep the tumblers moving smoothly in dusty or wet environments.
