The Tamiya 9803230 front direct cup is a focused upgrade for the TRF420 chassis that helps improve drivetrain response. It is suited to racers and tuners who want reliable, predictable power delivery under load.
Crafted to match the TRF420 layout, the direct cup reduces unnecessary friction and helps the front drivetrain deliver torque more evenly. That results in a crisper feel through corners and during throttle transitions.
Constructed to withstand the demands of circuit running, the component is a solid choice when durability matters. Regular inspection and fitting with correct lubrication will keep the unit performing session after session.
