Fits BMW S55 engines. This bundle requires drilling & modification. This is a stage 3 kit. 

Included:

* 4 pin type One piece S55 crank hub (forged steel) 
* Genuine BMW N55 Crank bolt. (S55 bolts are full threaded, while N55 bolts are only half threaded; otherwise, there is no difference between them.)
* Drill fixture tool with bolt
* Drill bit

* This WILL NOT fit N54 engines!
* We selected our drill bit for the optimal hardness to carry out this job. We don't offer here unbreakable drill bit! You can snap it so you must be very gentle and slow when drilling your crank. 
* We do not offer refund & partial refund for snapped drill bits or misaligned fixtures. You are solely responsible for the drilling procedure and the accurate timing of the hub therefore we highly recommend you to find a machine shop or a BMW specialist to install this hub.

* 2 Years warranty.
