Lightweight Upgrade for YD-2: Yokomo Y2-501GSAA

The Yokomo Y2-501GSAA Aluminum Drive Cup is built for the YD-2 gear differential to lower rotating weight and refine throttle response. Machined from lightweight aluminum, it helps reduce inertia at the driveline while the integrated resin protector limits wear on the dogbone side for longer service intervals. This is a practical upgrade for racers and hobbyists seeking crisper acceleration and dependable durability.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How does this part change throttle response?

By reducing rotating mass, the drive cup lets the motor and drivetrain react quicker to throttle inputs, producing a sharper and more immediate acceleration feel.

Will the resin protector prevent dogbone damage?

The resin protector reduces direct metal-on-metal contact and absorbs some wear, but routine inspection and replacement when worn will keep performance consistent.

Is installation difficult for a club racer?

Installation is straightforward with basic tools; remove the old cup, fit the new unit, and check dogbone alignment and set screws for secure operation.
