Precision aluminum pulley for chassis upgrades

The 3Racing Aluminum Differential Pulley Gear T39, model number 3RAC-3PY/39, is a precision machined part intended to improve drivetrain consistency in RC vehicles. Constructed from quality aluminum, this pulley balances strength and lightness for day-to-day hobby use and upgrade projects.

Top attributes of the 3Racing pulley

Material: High quality aluminum for dependable wear resistance without excess mass.
Tooth Count: T39 layout designed to keep power transfer smooth and predictable.
Compatibility: Works with many RC platforms where a T39 pulley is specified.
Function: Helps the drivetrain run more efficiently, aiding consistent lap times and reduced drivetrain lash.

Will this pulley fit my belt or shaft setup?

Check your vehicle service manual or measure the existing pulley and mounting interface. The 3RAC-3PY/39 matches standard T39 spacing, but shaft diameter and mounting method must be confirmed.

How does aluminum affect performance compared to plastic?

Aluminum improves durability and resists deformation under load, which helps maintain reliable engagement and smoother power delivery over time.

Any maintenance tips after installation?

Keep the pulley clean of grit, check fasteners after the first few runs, and periodically inspect teeth for wear to get the best service life from the 3Racing pulley.
