With the MRT Engineering ATI Super Damper Installation Kits you make your M30, M50, M52, M52TU, M54, S38B36, S52 or S52US engine fit for serious performance increases! The strong crankshaft hub made of CrMo tool steel allows the use of an ATI Super Dampers. This reduces or even eliminates crankshaft torsional vibrations by damping, especially at high speeds. The result is a significantly more accurate detection of the crankshaft signal. In addition, the Super Damper prevents the crankshaft bolt from loosening due to vibrations and effectively protects against problems with the oil pump.
Another advantage is the weight saving, which leads to better acceleration and deceleration, making the engine even sportier.
