Frequently Asked Questions

Will this fit my Twin Cam 88 engine?

No — this is the inner cam chain for Twin Cam 96/103 motors. Twin Cam 88 engines use a different part number.

Do I need to replace the cam chain tensioners too?

Tensioners wear independently of the cam chain. Inspect tensioners during service; replace if leaking, rattling, or slack cannot be reduced.

How do I know if my cam chain needs replacement?

Listen for a rattling noise at cold startup or idle. If slack persists after tensioner inspection or adjustment, the chain likely has stretched and needs replacement.

Is the cam chain guide included?

No — the guide is sold separately. Many shops replace the guide when doing cam chain service to ensure the chain runs true.
