Tamiya Aluminium Diff Holders 0.8 offset *2

The Tamiya Aluminium Diff Holders 0.8 offset (2pcs), part HC-22078, are precision aluminium mounts that secure the gear differential while enabling accurate belt tension adjustment on TA-08 and TRF420 platforms. Replacing the standard plastic holders, they increase rigidity, limit deformation under load and promote smooth, consistent rotation. Laser engraving clearly distinguishes them from Item 22079 (0.5 offset).

Features

• Aluminium Differential Holders x2.
• Rigid aluminium construction securely holds the belt-tension notch to reduce flex and ensure smooth rotation.
