Yokomo Z2-300SRF Steel Rear Suspension Mount (RF) for YZ-2 — steel rear mount for YZ-2 2WD off-road chassis  [Z2-300SRF]

Steel rear suspension mount for YZ-2

This steel rear suspension mount (RF) is an RC-scale replacement part designed for YZ-2 2WD off‑road chassis. The unit replaces a standard rear mount and is intended to shift mass slightly lower in the chassis compared with typical aluminium pieces, changing rear traction and handling balance without altering geometry.

Fit and installation are straightforward for anyone familiar with YZ-2 rear-end servicing: remove the original rear mount, transfer any bushings or spacers, and secure the steel RF mount using the chassis' existing mounting hardware. Verify thread engagement and torque to the same levels used for the factory part to avoid fastener loosening during running.

In tuning terms this heavier steel mount is a simple tool to influence rear-end behaviour. Adding mass low on the chassis tends to increase rear traction and can make the car feel more planted through low-speed corners and on loose surfaces; use it in combination with spring and damping changes to dial the balance you want for specific track conditions.
