Engineered Differential Housing for YZ-870C

Designed for club and competitive racers, the Yokomo YZ-503GH differential case provides a sturdy outer housing for the 34T gear assembly. Built to mate precisely with the YZ-870C chassis, it supports steady power transfer and predictable drivetrain response under race conditions.

Top Features for On-Track Performance

Compatibility: Manufactured specifically to fit the YZ-870C chassis for accurate alignment and installation.
Durability: Engineered to resist wear from sustained high-load running and repeated race use.
Performance: The 34T pulley arrangement helps distribute torque more evenly, improving cornering stability and traction control.

Will this drop into any other Yokomo chassis?

This case is made to the geometry of the YZ-870C and is not a direct fit for other Yokomo models without modification.

What routine maintenance keeps the diff running smoothly?

Regular inspection, fresh grease or diff fluid as recommended, and checking for gear wear will extend service life and retain consistent performance.

Does the 34T pulley require different belts or tuning?

No special belt is required if using the stock YZ-870C setup, but you should verify belt tension and alignment after installation to prevent premature wear.
