Stock Primary clutch bolts can break under elevated stress allowing the clutch/crankshaft/governor cup taper to uncouple causing costly damage to clutches, structure and the engine crankshaft. The Ultimate clutch bolt was developed to eliminate this problem. The 630 "Ultimate" bolt is made from ultra-strong 200,000 Psi material that provides a massive improvement in clutch bolt and clutch/crankshaft taper stability and holding power.
The ULTIMATE bolt directly replaces the OEM Can Am Ryker primary clutch bolt and uses the stock belleville washer. This bolt works with OEM clutches, aftermarket clutches that utilize the stock OEM length primary bolt.
