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.

These pulleys are precision made from domestic USA 6061-T6 Billet Aluminum. They have undergone thousands of hours in testing, race use, and street miles accumulated to show these pulleys work great and give you the edge.

This 3 Pulley Race Set is a very popular choice: just like the 2 pulley set, a precision power steering pulley and water pump pulley are included, but VAC includes an additional underdriven alternator pulley for maximum power output on the track.

BMW vehicles are prone to oil separators freezing in cold weather if driven before the engine is fully warmed up. This can lead to a howling noise followed by multiple oil leaks. The crankcase breather valve vents oil vapor from the engine block to the valve cover, but condensation can sometimes cause it to freeze, leading to a failure of the entire oil separator system, causing it to crack and break down. To prevent damage to your engine, it’s best to replace all components of the oil separator system at once. Replacing everything ensures reliable performance and durability. Remember to also order a valve cover gasket to make the replacement process easier.
