Fine-Tune Shifting on the TG10-Mk.2 with Tamiya 51141 - TG10-Mk.2

The Tamiya 51141 Dual-Speed Transmission Spring Kit is built to refine shift feel on TG10-Mk.2 chassis. These springs give crisper gear engagement and greater reliability under sustained high-speed use, making them a practical upgrade for competitive RC drivers who want consistent performance lap after lap.

Materials and Performance Benefits

This kit uses resilient spring wire and accurate tolerances to stabilise the dual-speed transmission. Expect steadier shift points and less slippage during aggressive acceleration. The springs are suited to track setups and tuning sessions where repeatable shift behaviour matters.

They are intended for the TG10-Mk.2 transmission and will install on stock gearcases. Minor trimming of surrounding shims is rarely required, but no major modification should be needed on a properly maintained gearbox.
Start with the factory preload and make small increments while testing laps. Increase tension if you notice delayed engagement, or soften if shifts become harsh under load.
Yes, they are manufactured for durability and consistent function under higher RPM and torque, but always inspect for wear after heavy runs and replace springs if deformation appears.
