When fitting a new camshaft drive-chain it is preferable to also fit new cam drive sprockets and this high quality none OE Cam Chain Guide Bar at the same time. This will avoid premature chain wear and help ensure accurate valve timing.
Order new cam chains and cam chain sprockets at the same time for long term durability.
