Rear Upper Arm Mount for Tighter Rear Control

The Yokomo Z2-30RUMWA is an aluminium rear upper arm mount built for YZ-2 DTM3 and CAL3 chassis types. Its wide profile is made to work with larger lower mounts and to reduce unwanted movement at the rear suspension.

Durable Alloy Design for Racing

Constructed from robust aluminium, this mount offers improved stiffness compared to stock plastic parts while keeping weight manageable. The wide format improves the relationship between upper and lower suspension points for steadier handling on track.

Compatibility and Installation Notes

This component fits models including B-YZ2DTM31-1 and B-YZ2CAL31-1 plus several SOR and ROR variants. It installs using the standard fixing points and is a practical swap for anyone upgrading their rear end.

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.

Does the mount require any machining to fit?

No machining is normally required when fitting to the specified YZ-2 DTM3 and CAL3 chassis. Check alignment and hardware lengths before tightening fully.

Will this make the rear feel harsher?

You may notice a firmer feel due to reduced flex in the mounting area. Small shock tuning can help retain compliance while taking advantage of the added stiffness.

Is this compatible with RTR versions?

The mount is listed as compatible with ROR-010RTR and related RTR model codes. Confirm the RTR chassis uses the same upper mount geometry before purchase.

Any tips for long term care?

Keep fasteners secure and inspect for thread wear after heavy use. Clean mounting faces and apply light anti-seize to prevent corrosion in coastal environments.

Can this part be used with carbon shock towers?

It can be paired with carbon towers if hole spacing and mount height match. Verify stack-up and adjust shims to avoid binding of the suspension links.
