Stiffer rear upper arm with optional ballast

This machined aluminum rear upper suspension mount is built for the YZ-2 2WD platform to clamp the rear upper arm more securely and reduce twist when the chassis rolls. The firmer attachment helps keep suspension geometry stable during lateral loads.

Two small removable weights (6g each) are supplied to increase load over the rear axle. Fitting one or both weights moves mass rearward to enhance rear traction and adjust cornering balance on lower grip surfaces.

Fitting is familiar to YZ-2 users: remove the stock upper mount, place the Z2-300RUW in position, and secure it to the existing chassis points. Recheck fastener torque after initial testing and after any impacts to ensure secure fitment.

Setup advice: try a single weight first to assess changes, watch for interference with travel or driveline parts, and routinely inspect mounting hardware after running sessions.

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.

What mechanical effect does the mount provide?

It reduces upper arm flex under roll, keeping pivot geometry more consistent so the rear tracks truer through corners.

Are the ballast pieces removable and tunable?

Yes. The two ballast pieces are removable and each weighs 6g to permit graduated increases in rear axle loading.

Can I use this on non-listed YZ-2 variants?

The item is intended for the listed YZ-2 models B-YZ2CA and B-YZ2DTM. Using it on other variants requires checking mounting geometry and clearances first.

Any recommended installation checks?

After installation, verify that suspension travel is not restricted, confirm there is no contact with drivetrain parts, and torque fasteners to spec after the first run.
