Precision Carbon Diff Upgrade

The Tamiya 84380 - F104 Carbon Integrated Diff Housing and Shaft upgrades the standard assembly on F104 cars with a bonded carbon rear shaft and integrated diff body. This lowers rotating weight and improves rotational balance, helping the car respond more predictably when you apply power. Relocating the spur closer to the joint sharpens throttle response for tighter lines.

Streamlined Mounting for Better Reliability

This integrated solution borrows proven layout ideas from 1/12 pan racers and the TRF101 kit, replacing set screw style fixing with a neater, stronger join. The assembly offers a snug fit and resists flex under load for consistent lap times.

Does the carbon shaft affect gear mesh?

The shaft lets the spur sit closer to the joint, which can change mesh slightly. Check and adjust the pinion or spur position to maintain correct engagement and avoid premature wear.

Can I reuse my existing diff plates?

Yes, the listed diff plates and disk springs are compatible with the housing, but inspect them for wear and replace if pitted or warped to keep diff action consistent.

Should I change my diff grease?

Fresh diff grease matched to your driving style helps preserve smooth rotation. Lighter greases aid responsiveness while heavier greases increase traction feel.
