Aftermarket alloy adaptor for Associated RC18T

This alloy main gear adaptor is produced for use with the Associated RC 18T platform and is supplied as a 1 pcs set with the required screws, identified as AR115. It is intended as a replacement or upgrade when the factory adaptor shows wear or when a stiffer fit between the spur gear and gearbox is preferred.

Installation notes: fit the adaptor onto the main gear shaft, align with the spur gear teeth, tighten the supplied screws evenly and confirm minimal axial play prior to final torque. Use the correct hex driver and moderate torque to avoid thread damage; recheck gear mesh after fitting.

Tuning role: during maintenance or rebuilds the adaptor helps keep the spur gear concentric with the gearbox, aiding reliable mesh and repeatable drivetrain response during running sessions.

Is this a direct swap for the original adaptor?

Yes, AR115 is designed as a direct replacement for the Associated RC 18T adaptor, provided shaft and spur dimensions match the original parts.

What tools are required for fitment?

A correctly sized hex driver and a small torque driver are recommended; avoid excessive force when tightening the screws.

Will this improve drivetrain longevity?

By restoring correct alignment and secure seating between spur and gearbox, the adaptor can help reduce premature wear when installed and set up correctly.
