Race-ready Tamiya 54158 - F104 Aluminum Differential Housing for RC Chassis  [54158]

Tamiya 54158 aluminum diff housing for cleaner drivetrain feel

The Tamiya 54158 Aluminum Differential Housing Set upgrades your F104 with a blue anodised casing that resists wear and improves visual appeal. It helps the diff run with less friction and is engineered for easy access during tune-ups. The housing remains secure even when wheels are removed, which simplifies troubleshooting between practice runs.

Compatibility advice and setup pointers

This kit suits both F104 and F103 chassis types. For F103 installations you must add item 54162 to correct axle length before fitting the housing. That extra part keeps axle geometry correct and avoids premature wear or driveline binding.
