55T Titanium Spur for RC18T

This 55T titanium main gear is an aftermarket spur compatible with Team Associated RC18T models, supplied as 1 pcs. It is a direct-replacement scale accessory intended for RC use only, built to function as the primary spur in the RC18T drivetrain.

In use, the titanium alloy delivers a good balance of corrosion resistance and wear life compared to standard steels, making it a sensible choice when durability and stable gear engagement are priorities. It is intended to sit on the chassis spur mount and mesh with the motor pinion, so correct alignment and proper backlash are important.

Installation notes: remove the existing spur, confirm the spline and mounting surface are clean, slide the gear onto the spur shaft and set pinion-to-spur mesh with minimal backlash and no binding. After final mesh adjustment, secure the gear with the original fastener and verify smooth rotation through the drivetrain sweep. Inspect clearance with nearby gearbox parts and add or remove shims as needed.

Tuning role: switching to a titanium main gear mainly targets long-term durability and more consistent mesh under extended running. After fitting, re-check mesh and drivetrain runout as part of your setup routine and review your chosen pinion size when tuning gear ratio for different track surfaces.
