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 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. Under U.S. Pat. 6,484,853 B1). Combine this kit with one of
our Shift Improvement modules and our gear train module to give you a strong durable transmission. We believe in sharing our knowledge and experience
with our customers. Our goal is to provide our customers with the information needed to choose the correct parts for thier transmission application.
