Introducing the 4N- Billet one piece crank hub! This crank hub has been developed as a one piece billet hub with induction hardened surface locking splines. This design creates splines on the mating surface of the crankshaft ensuring a zero chance of slipping. We sent this hub out to get tested on a customers single turbo M4 GT4 build conversion. Testing has been done with our CH all the way out to 8,500 rpm and 900whp in a circuit racing environment. That is the harshest conditions possible. Testing has shown great results and a reliable and easy to install locking CH solution!
The current price listed is our presale pricing. Once we are out of stock, presale will be over.
More notes below.
- higher strength CH bolt included with a nord-lock washer.
- one piece design with induction hardened splines and sprockets
- no holes required to drill into the crank. No metal shavings to clean out!
- This design will maintain a straight and true runout vs a pinned style hub which can wobble off center or potentially shear pins
- oil pan removal not required for installation. That means time and labor saved!
