Upgrade the FFEX drive with a machined pinion

The 3Racing FFEX Aluminum Pinion Gear SAK-F70 is intended for the KIT-FFEX and gives a durable, light alternative to stock pinions. With an 8 pitch design and 17 teeth, the pinion supports steady power delivery and reliable mesh under race conditions.

Benefits of an aluminium pinion in racing

Aluminium reduces rotating mass which can sharpen throttle response while keeping acceptable strength for competition use. The 17T layout provides a useful compromise between acceleration and top speed for varied track layouts.

Usage and compatibility notes

Designed for the 3Racing FFEX chassis, this pinion fits the stock drive arrangement for straightforward installation. It is a go-to choice when tuning gear ratios for specific tracks or refreshing worn drive parts.
