The Tamiya 50699 B Parts are made for the TA03 platform, compatible with TA03R and TA03R-S variants. Built from Delrin, these rear gear case components focus on wear resistance and smooth drivetrain movement so you can tackle varied surfaces with confidence.
Delrin delivers toughness with low torque loss, helping gears run cleaner and stay aligned. That means less frequent swapping and steady performance across club runs or backyard practice.
These parts copy the original TA03R and TA03R-S geometry to make fitting quick and predictable. They are ideal for routine service work and for owners who want dependable spares without complex mods.
