The Kyosho TF258 Aluminium Main Gear Holder is a sensible upgrade for club and race drivers running the TF7. It tightens the gear mounting area to reduce slop and keep the driveline behaving predictably lap after lap.
Crafted from solid aluminium, the TF258 improves resistance to bending and keeps the gear mesh steady under load. This precision is important for reducing premature wear and maintaining consistent power transfer.
Aluminium provides a good compromise between stiffness and low mass compared with heavier steels or flexible plastics. Fitting the TF258 can lead to smoother engagement and less drivetrain noise over time.
Engineered for the TF7 series, the Kyosho TF258 mounts using the chassis original fixings and should not require modifications. That direct fit helps you get back to fine tuning rather than fabrication.
