Tamiya 51649 TRF420 Tunable Gear Differential Set for Precision Handling  [51649]

Track-Focused Tamiya TRF420 Gear Differential Upgrade

The Tamiya TRF420 Gear Differential Unit Set from the Tamiya Spare Parts Series is made to sharpen the handling characteristics of your RC racer. It gives drivers a compact, serviceable option to improve balance and predictability on technical layouts.

Core Advantages of the Gear Differential

• Lightweight Design: The differential pulley and case were redesigned to save 1.5g, lowering rotating mass for crisper response.
• Enhanced Oil-Tightness: Improved seals help keep lubricants contained, reducing the need for frequent maintenance.
• Compatibility: Compatible with TRF420, TRF419, and TA07 models, offering flexibility across Tamiya platforms.

Fitting Notes for TRF419 and TA07

When fitting this unit to TRF419 or TA07 chassis, use bearing shims to set the correct bearing position. The Tamiya RC 10mm Shim Set (Item 53588) is recommended to achieve a smooth installation and avoid undue preload.
