Sharpen Rear-End Stability for YZ-2 DTM

The Yokomo Z2-300RUMA Aluminum Rear Upper Arm Mount is a practical upgrade for 2WD off-road YZ-2 DTM drivers seeking reduced flex and more predictable rear roll. Machined from durable aluminum, it keeps the upper arm secure under load and helps maintain consistent geometry through aggressive cornering.

Compatibility Across YZ-2 Models

This rear upper arm mount fits a range of YZ-2 variants, including B-YZ2DTMW, B-YZ2DTM, B-YZ2DTM2, B-YZ2CAL2, B-YZ2T, B-YZ2DTM2S, B-YZ2DTM3, and B-YZ2CAL3. Its fitment makes it useful for pilots who run multiple YZ-2 chassis versions and want uniform handling upgrades.
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 does aluminum construction affect handling?

Aluminum increases stiffness at the mounting point, cutting unwanted flex in the upper arm. That reduced movement translates to a more stable rear end and crisper response through turns.

Is installation difficult on a stock YZ-2 DTM?

Installation is straightforward with basic hand tools. You typically swap the stock mount for this part using the original hardware, though a small file or light cleaning may help alignment.

What setup changes should I try after fitting this mount?

After fitting, try small adjustments to rear shock damping and toe settings to balance the stiffer rear. Many users prefer slightly softer rear rebound to retain traction while benefiting from reduced arm twist.
