Upgrade the holding power of your 10R80 transmission with this Raybestos GPZ FNS(friction and steel) kit. The 10R80 has proven to be a great transmission but like most factory units it struggles with power adders available today. If you are making north of 700rwhp you are ready for this upgrade. We offer the kit with just the Frictions and Steels but additionally PBH has an install kit to help your builder get the job done. The install kit comes with needed seals, hardware, and new filter.

Included in the kit:

  • Complete GPZ friction set
  • All needed Steels

Works on all 2018-2023 Mustang 10R80 transmissions
