Built to support steady gear engagement, it helps with consistent power distribution and improved predictability on technical tracks. Fit it when you need a rugged, correctly shaped case to replace a damaged or fatigued original.

Does the case include mounting hardware?

The part is the differential case itself; confirm what fasteners you have from your kit or spares, as some builds may reuse existing screws and pins.

How do I check gear mesh after fitting this case?

Install gears and bearings, set the pinion to spur spacing with a feeler or paper method, then run the drivetrain by hand to ensure smooth engagement without binding.

Is this suitable for regular club racing?

Yes, when installed and maintained properly the Tamiya 51121 - TG10-Mk.2 provides consistent diff behaviour suitable for club level competition.

What should I inspect during routine service?

Check for hairline cracks, bearing play, and gear tooth wear. Clean old grease and relubricate with suitable diff oil as needed.

Can this case be used with different diff oils?

Yes, oil choice affects diff feel; select oil weight based on handling goals and follow recommended filling procedures.
