59T Service Spur for RC18T Tuning

Engineered as a service-level 59-tooth plastic spur for Team Associated RC18T-based setups, this part restores correct tooth geometry and consistent engagement for controlled testing and race-day resets.

Technical fitment: inspect gearbox interfaces and the mating pinion for wear before installation, establish a measured mesh and torque the carrier to spec, then rotate the drivetrain manually to verify free, even rotation. Replace compromised bearings or pinions to avoid accelerated spur degradation.

Performance and setup: use this 59T spur to return the vehicle to standard drive ratio after gearing trials; maintain correct backlash to ensure repeatable throttle feel and minimal drivetrain lash for sharper lap-to-lap consistency.

Service recommendations: plastic construction reduces rotating mass while offering adequate durability for tuning sessions; monitor for edge chipping after impacts and replace the component if the tooth form deviates from nominal.

Compatibility: Team Associated RC18T chassis.

How does this spur affect lap-to-lap consistency?

Using the correct 59T spur preserves the intended drive ratio and predictable gear engagement, which helps maintain consistent handling and throttle response between runs.

What checks should be part of a tuning session?

Before track testing, verify spur and pinion tooth profiles, confirm bearing play is within tolerance, set gear mesh to a repeatable setting, and perform a manual spin check for smooth engagement.

When to choose a different spur material?

If you require higher durability for aggressive off-road or frequent heavy impacts, consider switching to a composite or metal spur; for tuning and standard race use, the plastic 59T offers a good weight-to-durability balance.
