Upgrade Drivetrain Durability with the 3Racing T37 Pulley

The 3Racing Aluminum Differential Pulley Gear T37, model number 3RAC-3PY/37, is a practical performance part for RC enthusiasts. Made from quality aluminium, it is intended to lower wear and maintain reliable rotation during demanding runs.

Stable Power Flow for Aggressive Driving

Built for drivers who push their setups, the T37 pulley from 3Racing helps keep power delivery predictable. The aluminium construction resists deformation so the pulley keeps its profile under sustained loads.

Features That Matter

Material: High-grade aluminum for increased durability
Compatibility: Fits many RC models to expand upgrade possibilities
Functionality: Enhances transmission of drive force and reduces component wear

Do I need new bearings when fitting this pulley?

Replacing worn bearings when upgrading to the 3RAC-3PY/37 is a good practice, but new bearings are not always required if the originals are in good condition.

Will this pulley change gear ratios?

The pulley preserves the tooth count associated with T37 specification, so it does not alter the designed ratio unless you change pulley sizes elsewhere in the drivetrain.

How often should I inspect the pulley?

Inspect the pulley after heavy sessions and then at regular intervals; look for nicks, looseness, or unusual wear and address any issues promptly to avoid drivetrain damage.
