If you're building a serious horsepower BMW engine, here's a proper solution to replace the old cranky damper wheel! No more broken harmonic balancers, loosen up crankshaft bolt or oil pump issues, a precise crank signal due to undamped solid trigger wheel. ATI / PCE super dampers are rebuildable and can be tuned with different hardness o-rings.
M52TU / M54 / S52, without trigger wheel
CrMo tool steel crankshaft hub to be used with ATI super damper
Lightweight 60-2 trigger wheel made of high tensile Domex steel
ATI super damper shown in the pictures is included
A/C pulley not compatible with the kit
Check/adjust the ignition timing after installing
Comes with mounting hardware
