The PRECISION RACEWORKS HI-PERFORMANCE ZF6HP21 MASTER KIT designed by our sister company Propulsive Dynamics combines all the necessary components for a complete performance transmission build into one complete package.
This kit has been tested and proven on cars around the globe from 600whp up to 957whp! We rate the kit at 800wtq because people expect a rating but the truth is we have never found the limit! These clutches will never be the cause of shift problems or problems holding power other components in the drive line will become the limiting factor.
That is why our kit is the #1 choice of everyone from weekend warrior to the most competitive racer.

Stack out option:
This option is for the customer that really want's to DIY the transmission but doesn't have any of the specialty tools or doesn't really feel up to the task at hand. This option includes everything listed above except we handle most of the assembly for you. For this option you simply remove the bolts holding the oil pump and remove the stack from the transmission (it slides out) we then assemble the guts you ship us and send them back your way. This option takes us about 48-72 hours from the time we receive your components until they are headed back your way.
