|In order to use the keyed components that SBD produce, your crank will need to have a 3mm wide key machined into it, this can either be carried out by us (CRK-DURA-KEY-MOD05) or we can provide information so you can have your crank machined locally.
We supply the key CRK-DURA-KEY at the correct length 44mm & width 3mm to suit the conversion allowing you to join all the components together.
If you are buying one of our steel crankshafts (see above), the key is machined into it as standard.
We have manufactured a new sprocket CRK-PLY-DURA-K that includes the original cam chain drive and oil pump drive gears, we have also machined a 3mm wide keyway for positive location to the crankshaft. The standard item relies on friction to hold it's location, which can cause issues in motorsport use. We produce these in large batches which means we have managed to keep the price of the component affordable and yet very high quality.
