Service Parts for Classic Tamiya Brat and Frog

The Tamiya 9005139 Differential Plastic Gear Bag provides the original-style gears needed to keep Subaru Brat and Frog models running. It fits models 84237, 58384, 58354, and 57756 and helps restore correct differential function in older kits.

Why the Plastic Gear Choice Works

Plastic gears deliver a sensible balance of resilience and lightness for period buggies, reducing stress on bearings while maintaining smooth engagement. They are suitable for collectors and active hobbyists seeking faithful replacements.

Do these gears match the original parts exactly?

Yes, this set is produced to match the original fit for the listed Subaru Brat and Frog kits, so installation should follow the factory layout for those models.

What lubrication is best for these gears?

Use a light synthetic grease on bearing surfaces and a small amount on gear mesh to reduce wear; avoid heavy oils that can attract dirt into the housing.

Can I upgrade to stronger gears later?

If you need extra durability, consider aftermarket hardened gear options but confirm tooth count and housing clearance before purchasing.

How often should I inspect the differential?

Check the differential after any heavy impact or after extended running; regular seasonal inspections help catch wear before it causes failure.
