Compatibility and Pin Details

  • Compatibility: YZ-4SF2 and compatible chassis models
  • Pin Hole Diameter: Inner Φ3.5mm, Outer Φ3.0mm
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.

Is this a direct replacement for the original arm?

For standard YZ-4SF2 mounts this is a direct-fit replacement, just verify the TypeB holes line up with your chassis.

What benefits will I notice on track?

Expect more consistent rear geometry which translates to improved traction consistency and predictable corner exits when set up correctly.

Are aftermarket pins required for upgrades?

Aftermarket pins are optional; use quality 3.5mm inner pins if you want tighter tolerance or hardened materials for longevity.
