Within this listing we offer 2 types of S55 crank hub upgrade. No drilling and drilling required. Please read below the details about the pricing and options.
It is a common problem with BMW S55 and N55 engines that timing jumps.
Jumping timing can cause catastrophic engine damage.
It is down to poor design by BMW (M2, M3, M4 engines). There are many versions of these crankshaft hubs. 2 pin, 4 pin versions require you to drill modify your crankshaft which carries a danger to damage your crankshaft if drilling process was not successful. There is also cheaper designs with spline shaft connection but it is still a two piece design.
We offer here the very last version of this S55 crank hub upgrade. There is no better version than the 1 piece crank hub.
It makes your engine bulletproof as the small cog is embedded the hub so it will never slip and never give you timing fault codes.
We offer the final crank hub upgrade which is made of heat treated forged CrMo material.
Along with this listing we include other important parts:
Base price includes the NO drilling kit:
* Latest/final crankshaft hub (one piece design)
* Capture plate with bolts
* M18 crankshaft stretch bolt (Genuine BMW)
Optional the 4-pin DRILLING REQUIRED - Stage 3 crank hub upgrade.
Tightening torque:
Crankshaft hub central bolt (M18): 100Nm + 270 degree
Bolt locking flange (8x M8 bolts): 20Nm + 90 degree
At extra cost we also offer the 4 pin S55 crank hub upgrade where we provide a drilling fixture. This is an absolute fail save version of the S55 crank hub upgrade. Your timing chain would snap before the shear force would damage the 4 pins so there is absolute 100% safe fixture to the hub. You must position & time your crank hub before making the drilling. We only send this option if you select it.
Optional upgrades to the upgrade kit (only if you add it above the add to cart button):
