Race Focused Pulley Gear Overview

The 3RACING Aluminum Differential Pulley Gear T31 (3RAC-3PY/31) is a value racing upgrade aimed at improving drivetrain predictability and component longevity. Its metal construction gives tuners a more consistent baseline for setup work.

Setup and Tuning Advantages

Aluminium construction reduces deformation under load, allowing tighter gear mesh settings and more repeatable behaviour across runs. This helps when refining throttle response and diff balance for competitive conditions.

Application Notes for Racers

Designed to suit many 1/10 scale platforms, the pulley is a low cost part for teams wanting a durable component that supports repeated track sessions. Check fitment and align mesh during setup for optimal performance.

How does the 3RAC-3PY/31 affect setup consistency?

Metal pulleys hold their shape better under heat and load, which reduces variation in mesh and drivetrain feel between runs.

Should I alter diff settings after fitting?

Minor adjustments to diff preload or oil weight may be beneficial to tune for the changed drivetrain stiffness; test and log changes incrementally.

Is this pulley suitable for repeated club racing?

Yes, it is well suited to regular racing use as a cost effective durability upgrade that supports consistent lap times and easier setup tuning.
