Boost Drivetrain Response with the 3Racing T37 Pulley Gear

The 3Racing Aluminum Differential Pulley Gear T37, model number 3RAC-3PY/37, is a focused upgrade for racers seeking better drivetrain reliability. Machined from quality aluminum, this pulley helps reduce drivetrain wear while keeping power transfer consistent during lap after lap.

Built for Consistent Power Transfer

Developed for hobbyists who tune for lap time, the T37 pulley by 3Racing smooths torque delivery and lowers long term component wear. Its aluminium construction balances strength with lightweight behaviour to preserve drivetrain dynamics under load.

Practical Benefits for Your RC

  • Material: High-grade aluminum for increased durability
  • Compatibility: Designed to suit a wide selection of RC models for flexible fitment
  • Functionality: Enhances power transmission and helps maintain drivetrain efficiency

Will the 3RAC-3PY/37 fit my existing pulley setup?

Check your vehicle's pulley bore and mounting pattern against the 3Racing 3RAC-3PY/37 dimensions before purchase. Many mainstream kits are compatible but verification avoids fit issues.

Do I need different hardware to install this pulley?

In most cases standard mounting screws work, but inspect the kit manual for any spacer or shim requirements and reuse OEM fasteners where recommended.

How should I maintain the aluminium pulley?

Keep the pulley clean of grit, periodically check for wear and ensure set screws remain tight. Light lubrication on contact points can reduce squeak but avoid excess grease.
