Rear gear case upgrade tuned for TA03 chassis

The Tamiya 50699 B Parts package fits the TA03 line, including TA03R and TA03R-S cars. Produced in Delrin, these rear gear case parts help reduce friction and resist wear so you can focus on setup and lap times rather than frequent rebuilds.

Why Delrin helps drivetrain consistency

Delrin gives a good balance of toughness and low surface friction, which keeps gear engagement steady and lowers the chance of premature wear. That makes it a sensible choice for weekend racers and track practice.

Accurate fit for TA03R and TA03R-S layouts

These parts are engineered to match the TA03R and TA03R-S mounting points for clean, predictable installation. They are useful for routine replacements and for keeping a car reliable between events.

Will these parts suit rough club tracks and short grass?

Delrin is durable and copes well with everyday club track surfaces, but avoid excessive impacts and check the case after rough landings. Regular inspection is recommended for off-road or rough-surface running.

Can I fit these without changing other drivetrain parts?

These rear gear case parts are designed to integrate with standard TA03 assemblies, so most of the existing drivetrain will fit. Verify gear mesh and bearing positions when reassembling to ensure correct operation.

Any quick tips for assembly to reduce gear lash?

Set a consistent mesh using a business card or shim method, and secure fasteners with thread locker if you race often. Small adjustments to pinion or spur height can eliminate play without adding strain.
