Precision pinion for FFEX drivetrain

The 3Racing FFEX Aluminum Pinion Gear SAK-F70 is produced for the KIT-FFEX to provide a solid, lightweight gear option. Constructed from aluminium and specified as 8 pitch with 17 teeth, it supports dependable torque transfer and repeatable mesh.

Why aluminium suits tuning setups

Aluminium keeps the pinion light which helps rotational response while remaining sufficiently strong for most racing conditions. The 17 tooth choice balances top speed and acceleration, making it versatile across different track surfaces.

Fitment notes and practical use

Specifically made for the 3Racing FFEX chassis, this pinion fits cleanly into the original gearbox arrangement. Fit it when changing gearing for a particular track or when replacing worn components to restore smooth drive.

Yes, the SAK-F70 is an 8 pitch pinion and should only be paired with an 8 pitch spur to maintain correct tooth engagement.
Keep mesh set correctly, avoid debris ingress, and check for wear regularly. Replacing the pinion at the first signs of rounded teeth prevents damage to the spur.
Aluminium pinions are not suited to hardening like steel. Polishing mating surfaces and keeping good mesh is the best way to extend service life for aluminium pinions.
