Performance rear diff: Tamiya 22040 TA08 Lightweight Ball Differential Set 37T OP-2040 - Race-oriented upgrade  [22040]

Upgrade the rear end of your TA08 PRO with a lighter ball diff

The Tamiya 22040 TA08 Lightweight Ball Differential Set 37T OP-2040 provides a lower-mass alternative to standard diffs, helping the TA08 PRO rotate more freely where traction is scarce. When mounted in the rear, it creates a controlled limited-slip characteristic that improves corner stability and throttle control.

Core components inside the set

The kit contains parts selected to cut weight and boost driveline consistency:

• Aluminum Differential Joints: Durable A and B joint elements for accurate operation.
• Lightweight Ball Differential Pulley: A 37T pulley crafted to be lighter without sacrificing durability.
• Differential Plates and Screws: Fitted plates and fasteners for dependable assembly.
• High-Quality Bearings and Steel Balls: 850 bearings and steel balls supplied for smooth, low-friction performance.
• Compatibility: Intended for TA08 PRO use and compatible with TA07 and TRF420 chassis families.

Setup recommendations

Install this ball differential to tame oversteer on slick circuits. If you face high-grip conditions, switch to an oil-filled gear diff to get firmer overall response and sharper turn-in.
