The Z Pak Is A Single-sided Clutch System With The Revolutionary X-32 Friction Material That Outperforms Both Single-sided And Double-sided Original Equipment Clutch Assemblies In Torque Capacity, Durability.
Raybestos Powertrain Featured Product Z Pak™
Z Pak™ is the patented, single-sided clutch system that outperforms OE in torque and heat capacity without coning. For new OEM platforms, the Z Pak design can reduce the overall size of the clutch pack for a smaller, lighter assembly with greater thermal capacity. On existing designs, the single-sided plate can increase torque capacity and reduce core temperatures for a significant reduction in hot spotting and greater clutch life. And Z Pak takes the heat without coning. When used with the revolutionary X-32™ friction material developed by Raybestos, the Z Pak™ system outperforms OE by as much as 30%.(*Mfg.
