アーム C ロッカーアーム

The valve rocker arm has a tough job, and eventually the case hardened tip will wear through, and your valves will no longer open correctly for optimum performance.

If you are already replacing your cam, then we do recommend new rockers as a matter of course. Like wise worn rockers can be indicative of worn or damaged cam lobes, so you may wish to check this out as well.

Many other items to help you achieve a perfect cylinder head overhaul can be found on the CMS web site, valve stem seals, cam chain adjusters, and much more.

It is always worth checking the model application list carefully before placing you order, this helps avoid the frustration of ordering an incorrect part number!
