MUGEN MTX-5 2nd gear 20T (7075 hard) by Arrowmax AM-MTX5-T2711  [AM-MTX5-T2711]

2nd gear for MTX-5

This 2nd-stage spur gear is an RC-scale replacement part aimed at Mugen MTX-5 owners who need a direct-fit spare or a durable option for gearbox tuning. The AM-MTX5-T2711 carries the 20-tooth designation and is described with a 7075 hard material in the product name, indicating a high-strength aluminum alloy suitable for repeated mesh cycles inside model gearboxes.

Fit and compatibility: the part is intended for Mugen MTX chassis gearboxes that accept the MTX-5 specification; verify the gear seat and axle spacing on your gearbox before installation. Installation checks should include gear mesh, endplay, and bearing seating to ensure smooth engagement and to avoid premature wear to adjacent components.

Tuning role: this 7075 option serves as a direct replacement to restore correct spur geometry or as a component in fine-tuning gear ratios. When swapping spur gears, maintain factory alignment, inspect mating pinion gears and bearings for wear, and recheck mesh under rotational load to confirm reliable operation.
