Bluestreak 6R80 Billet Planetary Gear

The Billet Planetary Gear made famous by MSR! The Bluestreak billet 6r80 parts are the next step in making your 6r80 able to support over 1000whp! They are a direct replacement of the weak stock parts and will not change any function of the trans or require any additional tuning.

The stock forward planetary has an inherent design flaw from the factory. In a stock 400whp application, it does a pretty good job. But, when you double or triple the power of your hot rod, it is only a matter of time before it will fail.

The side planet gears ride on a thrust washer which is oiled through the center bearings of the gears. Under high load the gears are forced downward onto the thrust bearing and the oil is pushed out! The gear will then overheat and friction weld itself to the planet carrier. Once that happens the carrier will break and the planetary will come apart, destroying the entire front half of your transmission.

Our replacement billet planetary is constructed of billet steel and has a remedy for this problem: The planet gears ride on a rollerized needle bearing, which is designed for this specific type of load and can operate normally with very minimal amount of oil.

Note: If you are on the 1^st Generation input shaft, you will need to update to the newer version from Ford to Run the Bluestreak Planetary, the change was made somewhere around the 2014 Model Year.  The updated shaft part # is 9L3Z-7F207-A.
