Racing grade centre pulley for controlled belt drive response

The 3RACING Aluminum Center Pulley Gear T18 is aimed at racers and tuners who prioritise predictable belt drive behaviour. Its aluminium construction helps reduce deformation under load and supports tighter control over belt tension and power delivery during competitive runs.

Technical fitment and role

Intended for 1/10 scale on-road chassis, this pulley serves as a durable replacement that aids in maintaining consistent drivetrain geometry. Using an aluminium pulley can stabilise belt tracking and contribute to repeatable handling across setup changes.

Setup advice for track use

When integrating the 3RACING Aluminum Center Pulley Gear T18 into a race setup, ensure precise alignment and repeatable belt tension measurements. Verify pulley runout and recheck fastener torque after initial laps to lock in consistent behaviour.

How does aluminium affect belt dynamics?

Aluminium reduces flex versus many plastics, which improves repeatability in belt tension and tracking. That stability can translate to more predictable throttle response under race conditions.

Are there specific checks for race preparation?

Confirm concentric runout, verify alignment with adjacent pulleys, and record belt tension values pre and post run. Small deviations can affect lap time, so consistency is key.

What maintenance regime suits competition use?

Inspect for surface damage between events, keep contact surfaces clean, and replace belts at the first sign of heel or glazing to preserve drivetrain efficiency.
