crankshaft - the heart of the engine

The crankshaft is one of the most important parts in any engine and must withstand heavy loads. The crankshaft converts the up and down motion of the piston into a rotary motion, which is subsequently transmitted to the gearbox. The main components of a crankshaft are journals, webs, pin and connecting rod. Crankshafts can differ in many characteristics - size of the crank webs, full circle crankshaft or advance crankshaft, connecting rod length, journal diameter, crankpin diameter, etc. ...

From Motoforce there are e.g. OEM quality crankshafts, which are basically identical to the original crankshaft, from Stage6 we carry e.g. the HPC Team Replica with 85mm connecting rod for 12mm piston pin, for extreme tuning projects there are high end racing crankshafts like the famous 2Fast with 44mm stroke and 90mm connecting rod which can withstand up to 20,000 rpm.

Choosing the right crankshaft to improve engine performance

To help you with your picking the crankshaft that will best support your engine setup, we have tested all possible and conceivable combinations of cylinders, crankshafts and exhausts, the main components of an engine, in order to offer you the best parts in our store.

We can offer you a huge selection of high quality crankshafts, there is something for every budget. If you are looking for a good value standard crankshaft because your original one has to be replaced - no problem, you will find it here. If you prefer a  tuning crankshaft whether slightly reinforced for entry-level tuning or a high-end crankshaft for racing - we got you.
