Tamiya 22040 TA08 Lightweight Ball Differential Set 37T OP-2040 - Low-Drag Rear Ball Diff for TA08 PRO  [22040]

Dial in rear traction on the TA08 PRO with this ball differential

The Tamiya 22040 TA08 Lightweight Ball Differential Set 37T OP-2040 offers a compact, lightweight solution to make the TA08 PRO more predictable on surfaces with limited grip. Installed in the rear gearbox, the set produces a controllable limited-slip effect that helps maintain cornering balance and throttle response.

What the kit contains

The kit packs the parts needed to reduce rotating mass and improve driveline feel:

• Aluminum Differential Joints: A and B joints are supplied for durable, accurate engagement.
• Lightweight Ball Differential Pulley: The 37T pulley is slimmed down to cut weight while staying robust.
• Differential Plates and Screws: Hardware for a secure, repeatable assembly.
• High-Quality Bearings and Steel Balls: Includes 850 bearings and matching steel balls for smooth action.
• Compatibility: Designed to work with TA08 PRO and is also compatible with TA07 and TRF420 chassis platforms.

When to fit this ball diff

Fit this lightweight ball differential when you need gentler slip at the rear on low-traction circuits. For high-traction conditions, a conventional oil-filled gear diff usually gives crisper steering and more predictable mid-corner bite.
