We are proud to provide only the best parts to our customers. This kit is an excellent kit for the stock to mildly modified
vehicle with a 3-4 clutch failure and needs a heavy duty upgrade of all friction components.
Raybestos Z-PAK Friction Steel Rebuild Kit:
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.
