If you're grappling with issues like crankshaft failures and oil pump breakdowns in your BMW 6-cylinder engines, you're not alone. Even seasoned mechanics can overlook the critical aspect of harmonic resonance control in these inline-6 motors, despite their optimal configuration.

Enter ATI Performance Products in collaboration with VAC Motorsports, presenting a solution in the form of new dampers tailored for BMW 2.5L, 2.8L, 3.0L, and 3.2L straight-6 engines found in various models like the E36 and E46 M3, E9X, and E6X, as well as newer Z3s and Z4s. These dampers effectively nullify crankshaft harmonic vibrations, paving the way for enhanced horsepower and torque output, alongside a reduction in internal engine wear. Say goodbye to issues like fractured oil pumps and timing chain mishaps! By pairing these dampers with a VAC accessory pulley, you seamlessly replace the OEM balancer. Featuring a 7” outer diameter and OEM-style timing alignment tabs, these ATI Super Dampers boast SFI 18.1 Safety Certification, ensuring they're competition-ready.

What sets the ATI SuperDamper apart? It's the remedy for vibration woes in inline 6 engines, especially those equipped with lightweight clutch and flywheel setups. Expect diminished wear on bearings, engine accessories, and oil pumps, all while being compatible with underdrive pulleys.

Included in the kit are the damper itself, a lightweight VAC Billet Crankshaft Pulley, along with all necessary mounting and installation hardware. Note that it's not compatible with S50B30 & S50B32 Euro Engines. For street/track vehicles with air conditioning, opting for the Additional A/C Pulley Option is imperative, given that the OE A/C pulley isn't compatible. Rest assured, all required mounting and installation hardware is included, and the entire package is proudly Made in the USA.

NOTE: Due to space limitations, the design of this damper will overdrive your components (water pump, power steering, and alternator) by approximately 10-13%; we highly recommend using underdrive pulleys in your setup Controlling the harmonic resonance of the BMW S14 engine is highly important as RPMs rise, but the ideal configuration of the 4-cylinder motor makes even the most experienced engine builders overlook some fundamental principles of engine harmonics that can be destructive. Harmonics destroy these motors by causing extensive oil pump and crankshaft damage, but the addition of VAC’s Harmonic Damper eliminates the unstable crankshaft harmonic vibrations that cause internal engine wear. By eliminating harmonic vibrations, your S14 engine will be able to produce more horsepower and torque with increased reliability. The VAC/ATI Harmonic Damper is made with an integral pulley, eliminating the need for the additional pulley other models require. Exceeds SFI 18.1 Safety Certification Eliminates problems with lightweight clutch and flywheel assemblies Controls destructive harmonic forces Reduces instances of bearing wear, accessory failure and oil pump failure Includes lightweight VAC Billet Crankshaft Pulley Made in USA ATI Performance Products, Inc. is located in Baltimore, MD, and specializes in producing and maintaining high performance products for street and track applications. Over the years ATI has earned a reputation for its cutting edge technology, attention to detail and rigorous testing under race conditions.

The vibration damper in the E70 X5 35d is a common failure item and can fail at as low as 60 thousand miles leaving you stranded. This kit includes everything needed to replace your vibration damper and service your drive belt system! Vibration Dampers (also called Harmonic Dampers or Harmonic Balancers) absorb and remove unwanted vibrations due to torsional twisting of the crankshaft. During cylinder combustions, the crank quickly flexes ever so slightly, resulting in resonance vibrations. These vibrations could lead to damage of the crankshaft or crank bearings over time if not accounted for. The vibration damper helps to eliminate these vibrations, thereby extending the life of your engine's mechanical components and preventing damage. If your vibration damper has failed, you will likely notice excess engine vibrations or shaking that will gradually get worse, especially around certain RPMs where the vibration resonance is most pronounced. This kit includes all of the components necessary to replace your damper with an OEM damper from Corteco, including belts, pulleys, hardware, and more. Also included in this kit is a brand-new line of specialty tools from Schwaben designed specifically for this replacement! You will get a Crankshaft Pulley Turner Tool, Stretch Belt Remover/Installer, T50 Alternator Wrench, and a 15/16" Pass-Through Socket, all included to make swapping out your old damper a quick and easy process! Standard tools you might need but are not included: 8mm Drill Bit (to use as flywheel locking pin) 32mm Fan Clutch Wrench - You may want a second 32mm to hold the coupler in place 24mm Box Wrench - For releasing tensioner Torque Wrench - To torque new crankshaft bolts Breaker Bar - to drive the crankshaft bolts further
