Restore Precise Differential Operation on 1/10 Tamiya Models

The Tamiya 50388 RD Differential Ball Plate Set fits 1/10 scale RC Formula 1 and two-wheel drive sport cars, including the FW-14 Williams Renault. Use this kit to replace worn thrust components and keep the diff operating smoothly during practice and events.

Parts Included in the Set

The package contains the essential pieces to maintain proper differential action:

Ball Thrust Bearing: One 1150 size bearing to reduce friction and support even rotation.
Thrust Washers: Two pieces to balance pressure across the thrust surfaces.
Disk Springs: Two 5mm springs to secure the correct preload setting.
Differential Spacer: One aluminum spacer to maintain correct gear spacing.
Steel Balls: Eight 3mm balls chosen for consistent rolling performance.
Pressure Disk: Two disks to distribute load evenly across the assembly.

Is the Tamiya 50388 suitable for competition use?

The components are genuine replacement parts intended to restore original behaviour. For competitive tuning, check setup and lubrication to match your track conditions.

How do I check for worn steel balls?

Inspect the 3mm balls for flat spots, rust or pitting. Replace any that show defects to prevent uneven diff action and premature wear on mating surfaces.

Can I mix these parts with aftermarket diff kits?

Many aftermarket kits use similar dimensions, but confirm bearing size and ball diameter before mixing components to avoid fitment or performance issues.
