Track-Focused Rear Upper Arm Upgrade

The Yokomo Z2-30RUMWA is a wide aluminium rear upper arm mount crafted for the YZ-2 DTM3 and CAL3 layouts. Its broader mounting footprint is intended to complement wider lower mounts and deliver a steadier rear response under load.

Precision Alloy Construction

Made from precision aluminium, this component offers long-term durability without a big weight penalty. The wide design helps maintain suspension geometry under aggressive driving, giving more predictable handling through corners.

Model Compatibility and Use Cases

This part fits several chassis variants including B-YZ2DTM31-1 and B-YZ2CAL31-1 as well as SOR and ROR model numbers. Installation follows stock mounting points and is suitable for those comfortable with basic RC maintenance.

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 combine this mount with aftermarket rear arms?

Yes, it can work with many aftermarket lower arms as long as the mounting geometry matches. Verify hole spacing and arm height before fitting to avoid binding.

Will the mount change roll characteristics?

The wider top mount reduces unwanted twist and distributes loads more evenly, which tends to reduce excessive roll and makes the car more predictable in quick transitions.

Is any setup change needed after fitting?

Expect to recheck camber and toe settings after installation since the arm positions shift slightly. Small shock or anti-roll bar tweaks can help dial in the new balance.
