  • Rear sealed monoballs of superior construction designed to replace factory rubber banana arm bushings.  In most cases the stock rubber bushings are worn out and cracked after 20+ years of wear and tear, greatly compromising the overall performance and handling of the car.
  • Provides smooth articulation of rear trailing arm (banana arm) with zero deflection under cornering loads.
  • Housings and misalignment spacers are precision CNC machined from billet Stainless Steel.
  • High precision and high load capacity internal spherical bearings are made in USA, not china.
  • Each monoball bearing is sealed on both sides with a Viton rubber gasket to prevent premature wear due to moisture or dirt contamination, ensuring long track or street life.
  • Rebuild kits are available to provide lifetime product support.
  • Complete installation instructions included with each kit.  Sold in pairs, completes one car.
