Technical Overview of the 55T Main Gear

This 55-tooth main gear is intended for the Associated RC18T platform and is supplied in titanium with an alloy adaptor to match gearbox interfaces. It is specified as a direct replacement spur where a 55T count is required to achieve particular gear ratios and drivetrain behaviour.

Installation notes: supplied as a single set, the alloy adaptor facilitates correct seating in varied gearbox housings. During fitment confirm pinion engagement, wave washer stack and shim setup, and verify centre mesh under normal suspension travel to eliminate binding or excessive preload.

Tuning notes: selecting this titanium main gear provides improved wear characteristics and maintains accurate tooth geometry under load, supporting repeatable drivetrain performance. The alloy adaptor ensures stable axial location when used with aftermarket gearbox configurations, useful when validating lap-time oriented ratios or long-duration reliability tests.

What inspection steps ensure correct mesh on fitment?

Set an initial light mesh with the motor pinion, verify axial alignment using the adaptor, then run through suspension travel to confirm clearance under load. Adjust shims or the washer stack as required.

Are there recommended checks after the first run?

Yes, re-check gear mesh and adaptor seating after a short test run as components may settle; look for burrs, debris or movement that could alter engagement.

What role does the alloy adaptor play in performance?

The adaptor provides consistent seating and alignment between the titanium spur and the gearbox interface, aiding repeatable mesh and reducing the chance of axial slippage in non-original housings.
