Reduce Rear Arm Twist on YZ-2 DTM

The Yokomo Z2-300RUMA Aluminum Rear Upper Arm Mount tightens up the rear suspension by securing the upper arm and cutting torsional flex. Its solid aluminum construction delivers consistent geometry under lateral loads, helping drivers predict and control rear-end movements.

Broad Compatibility with YZ-2 Line

This mount is compatible with many YZ-2 models, such as B-YZ2DTMW, B-YZ2DTM, B-YZ2DTM2, B-YZ2CAL2, B-YZ2T, B-YZ2DTM2S, B-YZ2DTM3, and B-YZ2CAL3. That makes it a convenient upgrade for hobbyists who maintain several YZ-2 variants.
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.

Do I need threadlocker when refitting the mount?

Using a medium-strength threadlocker on steel-to-aluminum fasteners is recommended to prevent loosening under vibration, while allowing future removal for maintenance.

Will this fit on carbon or aftermarket chassis plates?

Fitment depends on the chassis layout; the mount is made for standard YZ-2 geometry. It can work with some carbon plates but check hole spacing and clearance before committing.

Does the mount change rear roll behaviour?

Yes, reducing mount flex alters rear roll characteristics, often making the car feel more precise. Expect a firmer rear feel which you can tune with anti-roll bars and shock settings.

What basic tools are required for installation?

A set of hex drivers, a small wrench for lock nuts, and a screwdriver for associated hardware are usually all you need to fit the part cleanly.
