CRK-DURA-KEY-MOD05

The standard crank assembly on the Duratec relies on a centre crank bolt being tightened sufficiently to hold the front pulley trigger wheel assembly, cam chain drive gear and crank in perfect alignment. In motorsport, this has several potential issues. It is quite likely that the loads and vibrations could cause these components to go out of alignment and at the very least cause a loss in performance, the chances are that everything could come completely loose causing catastrophic damage to your engine.

SBD offer a range of components and services to ensure perfect alignment for complete accuracy, this also helps to make the engine easier to assemble and removes the reliance on the crank bolt keeping everything aligned.

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 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 CRK-DURA-2.0L01, the key is machined into it as standard.
