Stellar Automotive Group Forward 6-Pinion Planet for Ford E4OD 4R100 1989-Up

Boost the durability and performance of your Ford truck or van with this forward 6-pinion planetary gear distributed by Stellar Automotive Group.

Acting as a direct replacement for OEM part #F81Z-7A398-CA, it fits E4OD and 4R100 transmissions from 1989 onward, with retrofit capability for earlier models using a compatible hub kit, tackling frequent failures like loss of forward gears, whining noises, slippage under load, erratic shifting, and premature wear in high-torque scenarios common to diesel and gas engines. This heavy-duty steel planetary assembly features six pinions for superior strength over standard 3- or 4-pinion designs, ensuring better torque handling, smoother operation, and reduced risk of breakdown during towing, hauling, or off-road use that often stresses stock components.

Compatible with a wide array of rear-wheel-drive and 4WD Ford models including F-150, F-250, F-350, F-450, Bronco, Expedition, Excursion, and E-Series vans equipped with 4.6L, 5.4L, 5.8L, 7.3L Powerstroke, 7.5L V8, or other engines.

Perfect for transmission rebuilds or upgrades on vehicles showing signs of gear train fatigue, harsh engagements, or diagnostic codes related to planetary issues, this part promotes long-term reliability and helps avoid expensive overhauls by maintaining precise gear engagement and power transfer mile after mile.
