Upper arm mount, rear - YZ-4

This rear upper arm mount is designed specifically for the 1/10 4WD YZ-4. It locates the top end of the rear suspension arm and is intended to work with the stock YZ-4 rear suspension geometry.

The unit includes a caster-adjustment bush offering three selectable caster settings: 0 degrees, 2.5 degrees and 5 degrees. Selecting a different bush changes the rear axle angle relative to the hub, enabling adjustment of steering return characteristics and high-speed stability without changing the arm itself.

Fitment follows the YZ-4 rear mounting points and uses the original chassis bolts; no chassis alterations are necessary. Keep the fasteners at the original torque values and recheck clearances after installation to ensure correct operation.

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.

Can I use my existing rear arms with this mount?

Yes, the mount is intended to work with the standard YZ-4 rear arms and the original suspension geometry, so existing arms remain usable.

Any advice on bolt torque and checks after fitting?

Refit using the original chassis hardware and set bolts to the same torque as the factory setup. After running, recheck tightness and clearances to confirm correct installation.
