CBS55-6001 CarBahn Autoworks S55 N55 Keyed Crank Hub Kit


CBS55-6001 CarBahn Autoworks S55 N55 Keyed Crank Hub Kit

The S55 engine is not designed to take a large increase in boost beyond the OEM spec. Due to the design of the crankshaft, it is known to have the timing chain sprocket spin on the end of the crankshaft, causing the cams to go out of time.

If you are planning a large power increase with bigger turbos, CarBahn Autoworks has designed a high-performance engine to handle very high outputs by pinning the cam sprocket to the crankshaft.

The keyed crank hub kit includes the Keyed hub, Crank bolt, Drill, drill fixture, and drill fixture bolt.

The original flawed design allows the timing gear to spin independently from the crank, especially when the motor is modified. Best case scenario the motor needs to be re-timed with new components. Worst case, the valves contact the pistons requiring a complete overhaul. Common symptoms are rough running and camshaft angle deviation faults. This crank hub uses OEM gears and hub machined and pinned to prevent slipping. Metallurgy is superior to most aftermarket sprockets on the market.

Estimated Installation Time: 18 hours

We are typically very quick and have a 24-48 hour turnaround time. Transit time depends on your order and which warehouse we are shipping from, but typical transit times are between 5-7 business days from one side of the US to the other.

Majority of the items we offer do ship free to the lower contiguous 48 states. States that require plane or boat to reach (such as Hawaii, Alaska, Puerto Rico, etc) do NOT qualify for free shipping. Please contact us to inquire about international shipping costs. During checkout, you will know which items ship free and which have shipping costs associated with them. In general, larger/heavier items will have additional shipping costs (body kits, wheels/rims, etc)

Even though everything can be shipped internationally, sometimes the cost is simply just too high and doesn't make sense to do so. We're here to make sure you have a great shopping experience, so if you have a product(s) you want to inquire about, please contact us at

Yes, we do price match reputable competitors in the marketplace. If you find a product cheaper elsewhere, please email us the (1) link of the product from our website and (2) the link to the competitor site. We will make an assessment on our end if we are able to price match or not and respond to you via email.

Typically you have 14 days to return a product you purchase when you change your mind. Damaged and improperly installed products are NOT eligible for returns. Shipping fees may be assessed and not refunded based on criteria as well as restocking fees. Please see our FAQ page for more details.

Unfortunate Kies Motorsports no longer does customer installs (with the exception of crank hubs - we still do thos inhouse). Our HQ is solely reserved for filming, office space, and shipping/receiving.
