Stiffen the Rear End for Tighter Lines

The Yokomo Z2-300RUMA Aluminum Rear Upper Arm Mount stiffens the upper arm mounting area to reduce unwanted movement during hard cornering. Built from aluminum for reliable strength, it helps preserve suspension geometry when the rear is under load.

Works with Many YZ-2 Variants

Designed for the YZ-2 family, this mount fits models including B-YZ2DTMW, B-YZ2DTM, B-YZ2DTM2, B-YZ2CAL2, B-YZ2T, B-YZ2DTM2S, B-YZ2DTM3, and B-YZ2CAL3. It gives consistent performance across different YZ-2 chassis configurations.
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 durable is the aluminium under off-road use?

Aluminium offers good durability and resists deformation better than plastic mounts. It can still scratch or dent in heavy impacts, but it will retain mounting integrity under normal racing stresses.

Will this require different shock settings?

Because the mount reduces rear compliance, you may want to adjust rear damping or spring rates slightly to maintain traction while benefiting from the sharper handling.

Are spare mounting screws included or should I reuse originals?

Many installers reuse the original hardware, but check screw condition and thread fit. Replace worn screws to ensure tight, reliable fastening between aluminium and existing components.
