Ford C6 Low Drag Planetary Gears Set, Front Clutch & Needle Bearings. Rebuild upgrade kit Fits C6 Transmission (1977- 1996)

TCI 425001 Ford C6 Low Drag Planetary Gear Set Upgrade for 1977- 1996 Transmissions

The TCI 425001 low drag planetary gear set is a proven internal upgrade for the Ford C6 transmission, designed to reduce parasitic drag and improve drivetrain efficiency.

This is a direct replacement planetary kit for 1977–1996 Ford C6 transmissions, converting the factory thrust washer setup to needle bearing operation, significantly reducing internal friction.

Less drag inside the transmission means more power delivered to the wheels, making this upgrade ideal for performance street, strip and high horsepower applications.

Why Upgrade Your C6 Planetary Set

The factory C6 planetary system uses thrust washers that create drag under load. The TCI low drag planetary upgrade replaces these with needle bearings, allowing smoother rotation and reduced friction.

Benefits include:

• Increased transmission efficiency

• Reduced parasitic power loss

• Improved durability under load

• Smoother internal operation at high RPM

This is a common upgrade in drag racing C6 builds and high performance street applications where every bit of horsepower matters.

These TCI Part# 425001 low-drag planetary sets include:
