Rattler Balancers

The Rattler® is an absorber that eliminates the root cause of torsional vibration. Effective for the entire RPM range, it extends crankshaft, bearing and valve train life. The unique design does not utilize viscous fluids and requires virtually no maintenance. Timing marks are etched onto the body and cannot move relative to crankshaft centerline. The Rattler® weighs less than most units of the same size and construction.

  • Integral timing marks can't move relative to crankshaft
  • Maintains maximum effectiveness at all engine speeds
  • No fluids, elastomers or friction materials; no pulley or crank trigger shims required
  • SFI 18.1 certified
