Under certain conditions, the N55 crank hub likes to spin, without warning and even when the engine is in perfect health. The engineers at Vargas saw and dealt with this problem time and again, and they saw fit to do something about it. This hub uses a proprietary "Spline Lock" technology that uses high tolerance machined splines which press into the crank, and positively lock the hub to the crank. The splines are machined in such a way that rotational forces drive the hub, and splines deeper into the crank meaning when the hub encounters a situation that would normally slip a stock hub the splined hub is driven into the crank to keep it in place (much like a splined extractor). Features: Installs the same as a stock hub Does NOT require the crank to be drilled for pins Manufactured from Harndered 17-4SS We suggest the Crank Hub System ONLY be installed by a qualified shop or technician. Timing tools are 100% REQUIRED if installed improperly engine damage may occur. DISCLAIMER: VTT and ECS are not responsible for any engine damage caused by improper installation, or misuse of the crank hub solution.

Anyone with a modified N55/S55 knows the risks involved with the OEM Crank Hub. When the engine simply can't handle the stresses its put under or the design is such that it simply does not support extreme conditions, issues can arise. Under certain conditions, the N55/S55 crank hub likes to spin, without warning and even when the engine is in perfect health. MMR has produced a EN36 machined billet one-piece crank hub heat treated with a 0.75mm case hardening which makes it extremely durable. Due to the one-piece design, it ensures that the friction plates cannot slip. This offers a huge jump in reliability when paired with a new properly torques crank bolt. Installation is requires no drilling or modification to the OEM crankshaft ensuring a perfect fit! Included in this kit is MMR's T-6061 machined billet aluminum capture plate anodized in their trademark finish. The MMR Performance capture plate secures the head of the OE crank bolt and prevents it from turning or being able to loosen. *Installation recommended by a professional shop or technician.

Anyone with a modified N54 knows the risks involved. Upping the performance of any engine can come with some inherent risk; if we add more boost but not fuel, detonation will occur (or worse).

When the engine simply can't handle the stresses its put under, or the design is such that it simply does not support extreme conditions. Enter the N54 crank hub.

Fortunately MMR Performance has released an upgraded version of their already stout single-piece crankhub, but this time offering a 4-pin dowelled location that locks onto the front of the crankshaft. This configuration eliminates the multi-piece crankhub with friction discs in favor of a more robust single piece crankhub. Recommended for high-powered cars over 700 Horsepower

Anyone with a modified N54 knows the risks involved. Upping the performance of any engine can come with some inherent risk; if we add more boost but not fuel, detonation will occur (or worse). Furthermore, improper installation, maintenance, or operation can turn a perfectly healthy engine into a paperweight. The worst failures, however, are the ones we don't plan for. When the engine simply can't handle the stresses its put under, or the design is such that it simply does not support extreme conditions. Enter the N54 crank hub. Under certain conditions, it likes to spin without warning, even when the engine is in perfect health.

This ARP Main Stud Kit is designed to replace BMW 11111735525 for the S14 B20, S14B23, S14B25, S14B27 engines found in the E30 M3. One significant advantage of these main studs is their ability to prevent main cap walk, which can occur when the main caps shift or move out of position, potentially causing damage to the engine. In addition, ARP Main Studs can safeguard the threads of your engine block, providing an extra layer of protection against potential damage. When opting for main studs instead of factory bolts, it's important to note that the engine builder should mic the bores. Using studs may require a line hone to ensure proper fitment and alignment. A line hone is a machining process that can be used to resize and reshape the main bearing bores, ensuring that they are perfectly round and concentric. This is crucial for ensuring proper oil clearance and preventing premature bearing wear. By mic'ing the bores and performing a line hone if necessary, engine builders can ensure that the main studs are installed correctly and that the engine will perform reliably and at its best.

The vibration damper, sometimes referred to as the crankshaft pulley, is a crucial part of the engine in your BMW. Not only does this pulley supply power to all of the belt-driven accessories on the engine, it also absorbs the shock of the engine while it is running to help give your engine a smooth, quiet idle. If you vibration damper is failing, it will usually present itself in the form of a squealing noise that sounds like a slipping belt. This is an indication that the rubber ring inside of the vibration damper has dried out and cracked, causing the pulley to slip. If your vibration damper has seen better days, it must be replaced in order to keep your engine running properly, and all of you accessories functional.
