T28 one-way centre pulley for precise drivetrain tuning

The 3Racing Aluminum Center One Way Pulley Gear T28, model number 3RAC-3PYW/28, is a value conscious upgrade aimed at competitive hobbyists focused on drivetrain refinement. Priced at $12.50, it provides a reliable component for teams and solo tuners looking to optimise power delivery characteristics.

Engineering benefits for racing setups

Produced from durable aluminium, the T28 offers a lightweight yet stiff replacement to support consistent torque transfer. Its one-way mechanism reduces driveline backlash during acceleration phases, aiding traction control and repeatable lap execution in race conditions.

Installation, fitment and tuning notes

The pulley suits a variety of on-road chassis layouts and installs with standard RC tooling. For best results, confirm shaft alignment and torque settings during fitment and verify free rotation under load to avoid binding that could affect setup balance.

How does the one-way action affect throttle modulation?

The one-way clutch smooths initial torque transfer on acceleration, which can improve modulation and reduce abrupt load changes felt at the wheels, aiding consistent corner exits.

Any setup checks recommended after fitting?

Verify concentric mounting, inspect for end float, and run a bench check under drive to ensure the pulley engages and disengages cleanly before track testing.

Is this part a common tuning path for 1/10 racing classes?

Yes, swapping to a machined one-way pulley is a common, cost effective upgrade to refine drivetrain behaviour without wholesale gearbox changes, especially for on-road classes.
