Reinforce the YZ-2DTM3.1 Rear End with Yokomo Z2-300R31A

The Yokomo Z2-300R31A is built for racers who want a firmer, more predictable rear assembly on YZ-2DTM3.1 and CAL3.1 cars. This rear upper mount, roll bar holder and gear box support is engineered to reduce unwanted movement and withstand race day stresses.

Track-Focused Design for Consistency

Made to fit the YZ-2DTM3.1 and CAL3.1 chassis precisely, the mount secures components to limit flex and preserve suspension geometry. Durable construction ensures consistent handling through corner exits and high speed sections.

Fits Multiple Supported Chassis

The part is compatible with a range of supported chassis including B-YZ2DTM31-1, B-YZ2CAL31-1, SOR-010, ROR-010, ROR-010RTR, ROR-010RTR-1, SOR-020, and SOR-020D, making it a practical upgrade for those working across different builds.
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.

Will this mount fit an existing YZ-2DTM3.1 rear assembly without modifications?

Yes. The Z2-300R31A is designed for direct fit to YZ-2DTM3.1 and CAL3.1 chassis and should install without trimming when used with standard OEM parts.

Does it change handling noticeably on high bite surfaces?

By stiffening the rear support and reducing flex, the mount helps the car track cleaner on high bite surfaces, which can improve rotation and exit stability for tuned setups.

Are there special maintenance steps for this part?

Inspect mounting hardware regularly for tightness and check the gear box area for wear. Replace any stripped screws and ensure fitment remains snug after heavy runs.
