This is the updated oil pump chain tensioner kit. In 1984, Porsche began using chain tensioners that rely on oil supplied by the engine's oil pump. These new tensioners do not fail like the older chain tensioners often do. The nice thing is that this kit is a bolt on upgrade for the older engines. This kit includes all hardware and gaskets, a must upgrade for all 911's up to 1983 or 930's. OEM Part numbers are interchangeable with 930105911912 as well as 93010591199.

Comes with a full 1-year unlimited mileage warranty against any defects.

Please Note: If you have a pre 1981 car you'll need chain tensioner spacers. We also have OEM chain wheel supports for left and right. Feel free to call us at 503 669 2277 with any questions you may have.
