The Tamiya 56529 Reinforced Joint Cup & Bevel Gear Set is made to strengthen the driveline of 4x2 tractor truck models. Heat-treated alloy construction increases resistance to wear, making it a sensible upgrade for heavier or frequently used trucks.
The updated joint cup and bevel gear improve rotation smoothness and load sharing across the drivetrain. Pin and axle ring retention reduces movement and helps prevent joint separation during demanding runs.
