Tamiya 22079 0.5 Offset Aluminum Differential Holders Pair OP-2079  [22079]

Better Belt Control with Tamiya 22079 Aluminum Differential Holders

For those aiming to improve handling on TA-08, TRF420 and TRF420X platforms, the Tamiya 22079 Aluminum Differential Holders replace the stock plastic pieces with machined aluminum and a 0.5mm offset for more consistent belt alignment and fit.

Stiffer Mounting for More Consistent Tension

These aluminum mounts secure the gear differential and allow precise belt tension adjustment. The reduced flex helps limit drivetrain movement under load and keeps rotation smooth. A firmer connection between the bulkheads and the chassis also helps transfer damper motion more directly.

Placement Tips for Different Track Grip

Set the holder position to match surface grip using these guidelines:

• High Grip: Use Item 22078 at the top.
• Medium/High Grip: Use Item 22079 at the top.
• Low/Medium Grip: Use Item 22079 at the bottom.
• Low Grip: Use Item 22078 at the bottom.

Fitment and Marking Details

The Tamiya 22079 is compatible with TA08R, TA08 PRO, TRF420X, and TRF420 chassis. Laser engraving on the parts makes them easy to distinguish from the 22078 item.
