The timing chain tensioner from the 1995 E36 M3 is a great upgrade for other Motorsport models - 1988-1991 E30 M3 and 1989-1995 E34 M5! This tensioner virtually eliminates the cold start-up engine rattle so common with the S14 and S38 engines. It makes the whole engine quieter and smoother. Any new tensioner will accomplish that but the S50 tensioner has several new features that make it superior to the original design. This unit also has a internally loaded spring, so installation is much easier than the old style tensioner (no need to squeeze the spring and hold it while installing). Includes oil seal ring (not pictured).

1985-1989 E24 BMW M635CSi M6 - M88/3, S38B35 engine
1988 E28 BMW M5 - M88/3, S38B35 engine

Kit includes Cam gear and valve cover gaskets. Better acceleration and improved torque for your M5/M6

Over time, accessory belts begin to wear out and crack. This can lead to the belt slipping, squeaking, or even snapping. Replace your belts and tensioners on a regular basis to ensure you don't end up stranded on the side of the road with a dead battery or over heated engine due to a bit of simple overlooked maintenance. This kit includes the belts and tensioner bar.
