The Tamiya 40509 Aluminum Differential Joint replaces weaker components on the GB-01 to offer improved wear resistance and steadier diff behaviour. Its aluminium construction helps the differential maintain smoother action under load.
Installing the Tamiya 40509 reduces slack in the driveline and promotes more even power distribution to the wheels. This can make steering responses and throttle control feel more reliable when pushing the car.
Suitable for both tarmac and mixed-surface sessions, this joint is a good choice for builders wanting a longer lasting part. Periodic cleaning and the correct diff grease will keep it performing well.
