The Tamiya 42267 - TRF 04 hard coat aluminum pinion gear is a practical upgrade for RC hobbyists aiming to tune drivetrain efficiency. Machined from light aluminium, this 37-tooth pinion improves power delivery while cutting friction losses within the 04 Module gearset.
The hard coat finish increases wear resistance so the gear stays serviceable through frequent use and racing sessions. Precision-cut teeth reduce binding and help maintain consistent meshing with your spur gear for reliable performance.
Made to fit any Tamiya model using 04 Module gears, the Tamiya 42267 includes a 3mm grub screw for secure attachment. Installation is simple and lets you experiment with different gear ratios without complex modifications.
