Drive upgrade for FFEX with machined pinion

The 3Racing FFEX Aluminum Pinion Gear SAK-F70 is built for the KIT-FFEX to give a durable, lightweight replacement pinion. Made from quality aluminum, this 8 pitch 17 teeth pinion is set up to deliver consistent power transfer and long service life.

Lightweight strength for close setup work

Aluminum construction keeps weight down while keeping strength where it matters, so racers can trim grams without losing durability. The 17T tooth count finds a useful middle ground between top speed and acceleration for club track and sprint formats.

Chassis fit and common use cases

This pinion is tailored to the 3Racing FFEX chassis for a clean fit and predictable mesh. Use it when tuning gear ratios for track conditions or when replacing a worn stock pinion to restore crisp engagement.

Can I run this pinion on non FFEX gearboxes?

This pinion is optimised for the 3Racing FFEX layout. It may fit other gearboxes with the same shaft size and 8 pitch specification, but check mesh and shaft dimensions before fitting.

How should I set pinion mesh for best life?

Start with a thin shim to eyeball clearance, then adjust to a snug mesh with a small amount of backlash. Proper mesh avoids early wear and keeps noise to a minimum.

Is aluminum better than steel for pinions?

Aluminum saves weight and reduces rotating mass, which helps handling and acceleration, but it can wear faster than hardened steel under heavy use. It is a strong choice for tuning and racing where weight matters.
