When you’re chasing big power, reliability in your 6R80 build starts from the inside — and the forward planetary is one area that can’t be overlooked. Bluestreak’s Billet Forward Planetary is a no-compromise upgrade designed to eliminate the failures often seen with the factory cast piece under high RPM and torque.

Built from premium materials and precision-machined in Australia, this planetary keeps the OEM gear ratio, meaning no special tuning is required. It’s a direct drop-in replacement for the stock unit, with no need for machining or case modification. Just better parts where they matter most.

Important Fitment Note:
This billet planetary is only compatible with the updated design input shaft (used in 6R80 units built after June 2014). If you’re working with a Gen 1 transmission built before 6/14, you’ll need to upgrade to the newer input shaft to install this part.

Why it’s worth it:

  • Handles extreme RPM and torque without failure

  • Keeps stock gear ratio — no tuning adjustments needed

  • Direct replacement — no machining required

  • Built to withstand the abuse of street, strip, and race use

  • Designed and manufactured by Bluestreak Performance in Australia

  • Compatible only with updated input shaft (post-6/14 Gen 2+ 6R80)

Works on all 2015-2017 Mustang 6R80 transmissions
