The Tamiya 50699 B Parts kit is intended for TA03 chassis applications, including TA03R and TA03R-S cars. Manufactured from Delrin, these rear gear case components aim to reduce friction and provide a robust contact surface to support routine servicing.
Delrin offers a combination of dimensional stability and low surface friction, which helps maintain consistent gear engagement. That stability can reduce the frequency of corrective adjustments on well-tuned cars.
Designed to the TA03 form factor, the parts align with the standard TA03R and TA03R-S mounting points for a tidy installation. They are useful as spare components for owners who prefer keeping an organised parts inventory.
