For Tamiya 4WD chassis Double Aluminum Double Rollers 18-19mm M4WD-36/LB by 3Racing  [M4WD-36/LB]

Double roller assembly for 18-19mm Mini 4WD applications

The M4WD-36/LB is a twin roller unit designed for Mini 4WD models that accept 18-19mm rollers. It is machined from aluminum and finished in light blue anodize, suitable as a direct replacement or a cosmetic upgrade for race and display cars.

Hobbyists and racers who need uniform roller diameter and tougher rolling faces will appreciate this part for tower or stabiliser setups. Combining two rollers on a single mount alters how the car interacts with guide rails and barriers when compared to separate single rollers.

Installation depends on your chosen chassis and the mounting hardware used. Check shaft length and spacer clearance before installing on Super-II, MA, MS, AR, FM-A, VS or other high-performance chassis. The item is specified for 18-19mm and a light blue anodized finish, with no motor, gearing, or other drivetrain changes implied.
