"Maximum Duty Planetary" 6 Pinion Reaction - Optional Ratios

MAXIMUM DUTY STRAIGHT CUT PLANETARY

The Max Duty Straight Cut Series offer increased strength properties consisting of 6 pinion reaction carriers, 4 or 5 pinion output carriers and a larger diameter heavy duty input ring gear. A new larger diameter billet steel shell was designed to accept the larger diameter, heavy duty ring gears. This larger diameter required “windows” to be machined to allow “park” to function.

It serves as a cornerstone upgrade that helps maintain precise gear timing, reliable torque transfer, and race-ready operation mile after mile, ideal for anyone pushing their TH400 beyond factory limits.
