Description
Designed specifically for BMW S55 engines, the Evolve solution is engineered to address a common issue and provide peace of mind for owners. The OE design has been known to "slip" or "spin" on tuned cars and to a lesser extent on completely stock cars. This can lead to at best the engine requiring retiming or at worst piston to valve contact and therefore an engine rebuild.

The Evolve S55 Crank Hub Fix is crafted to resolve the inherent weakness of the stock crank hub design ensuring long-lasting durability. The two-piece construction makes for easier installation while the 4 pin interface with the OE Crank provides an extra layer of security.

Crafted from EN36 a material which is commonly used to manufacture crankshafts in automotive and aerospace industries, the Evolve S55 Crank Hub Fix is engineered to withstand extreme conditions and deliver reliability under intense stress. A drill bit and alignment guide are provided as part of the kit to make installation for a trained professional easier.

Whether you're a performance enthusiast, a track day aficionado, or simply seeking to protect your investment, the Evolve BMW S55 Crank Hub Fix with the 2-Piece 4-Pinned Crank Hub is the ultimate in preventative care.

Description
The Gintani Crank Hub for the S55 engine is the only One Piece crank hub on the market, meaning insurance against the chance of the crank hub “slipping” or “spinning” and un-syncing the relative angles between the crankshaft and camshafts (this can mean engine failure which will cost upwards of $20,000 to replace or at the very least leave you stranded and un-driveable until the crank hub is replaced and engine is retimed). This SCH failure has been seen on both modified and stock S55 engines. If you are modifying your car, or even driving it in a spirited manner on the road or track, then upgrading your crank hub is highly recommended.

Description
The VAC/ATi design and developement team brings harmonic control to the BMW S55 engine.

If you are breaking crankshafts and oil pumps, the cause may be a mystery to you as it has been to many customers. We know that controlling the harmonic resonance of the BMW 6 is highly important as RPMs rise, but the ideal configuration of the inline-6 motor makes even experienced engine builders overlook some fundamental principals of engine harmonics that can be destructive.
FACT: harmonics CAN destroy these motors despite their ideal 'inline six' balance. Popular word on the street says the OEM units do not fail, but many clients prove otherwise. Some racers would bring a few spare units to each event -not any more. Simply fitting their engines with the VAC damper solved their issue and restored confidence in the powertrain.

These VAC exclusive dampers eliminate nearly all unstable crankshaft harmonic vibration which allows the engine to produce more horsepower and torque, maintain reliability and ensure internal engine wear is minimized.

This new design has an integral pulley so there is no need for an additional pulley as the other models do.

VAC's ATI Super Dampers exceed SFI 18.1 Safety Certification and are approved for competition
Eliminate problems with inline 6s fit with lightweight clutch and flywheel assemblies
Control destructive harmonic forces
Reduces instances of bearing wear, accessory failure and oil pump failure
Made in the U.S.A.
