BMW E30 E36 Z3 m42 m44 318 is ti sprocket crankshaft

We offer the crankshaft sprocket of the m42 and m44 engines in an improved version.

What was improved?

- The basis is a higher strength base material for highly stressed machine parts. This provides the tough core of the sprocket and has almost twice the tensile strength of the original sprocket.

- In addition, the entire edge area of the component was modified by a special quenching and tempering process. This has increased corrosion resistance and surface hardness which greatly improves wear resistance and longevity.

- Milling with modern multi-axis machining centers has significantly improved surface quality and angular accuracy compared to mass-produced sprockets (often a push process). This results in larger contact surfaces between the teeth and the chain rollers, which contributes to lower surface pressures, thus better power transmission and minimized chain wear.

- A more stable ("blunter") tooth contour was chosen.


Scope of delivery:
- 1x improved crankshaft sprocket for m42 and m44 engines
