Precision alignment tools are only effective when they move smoothly and hold their position without "slop" or play. The Longacre 52-78245 Replacement Shoulder Bolt & Wave Washer is the factory-spec hardware kit required to maintain the pivot points on your Longacre caster/camber gauges and alignment adapters.
Over hundreds of uses, the original shoulder bolt can experience thread wear, and the wave washer—which provides the critical tension needed for smooth, controlled movement—can lose its "spring" or flatten out. This kit allows you to rebuild the mechanical pivot of your gauge, ensuring that your caster sweeps are fluid and your measurements remain repeatable. It is an essential "small part" that prevents a high-end tool from feeling loose or inaccurate.
