Tamiya TB-03 OP-1054 Aluminum Motor Adapter Upgrade  [54054]

Stiffen Your TB-03 Chassis with the Tamiya OP-1054 Adapter

The Tamiya OP-1054 Aluminum Motor Adapter is a direct replacement for the K-6 plastic motor mount in TB-03 kits, giving a tougher mounting point for your motor. It is well suited to high-output electric motors and works particularly well when combined with a .04 module spur gear to help extend drivetrain life.

Aluminum Advantages for Performance

Aluminum offers increased rigidity and better heat dispersion compared to plastic, which helps keep the motor seated correctly under load. That extra stiffness reduces flex and vibration so gear mesh stays consistent during spirited runs.

Quick Installation Notes

When fitting the adapter, tighten mounting screws to the recommended torque and check motor alignment before final runs. Using the OP-1054 with a .04 module spur gear will often give smoother wear and improved longevity for gearbox components.
