Features & Benefits

  • Heavy-duty friction material provides the firm physical grip needed for smooth gear changes
  • Complete assembly format replaces the entire synchronizer section for a more reliable rebuild
  • Precision-machined hub ensures a perfect fit on the transmission shaft for steady power flow
  • Eliminates gear grinding by allowing for a fast and synchronized match of internal speeds

PAI Synchronizer Assembly

The PAI Synchronizer Assembly is designed to restore smooth gear engagement in Mack T200 and T300 series gearboxes. This unit features high-strength friction material and a precision-machined hub that provides the physical grip needed to match gear speeds during shifts. The PAI EM25040 comes as a complete assembly rather than a loose disc, ensuring all internal pins and springs work together for a crisp, zero-play feel at the shift lever. Built for the high-torque demands of vocational trucks, this assembly maintains a steady and reliable link between the main shaft and the gears to prevent the grinding and hard shifting that leads to gearbox wear.
