Rear mount details for YZ-4 setup

This aluminum rear suspension mount serves as the right-rear replacement specifically for the Yokomo YZ-4 scale touring chassis. It is machined for rear-chassis installation and designed to work with S4Arm-length suspension arms so the rear track meets expected dimensions.

Fit this component when you need a clean mounting surface to control rear track width without modifying suspension arm geometry. The unit ships as a bare mount sized for YZ-4 rear mounting points; consult the compatibility list below to verify the supported B-series models.

Do I need to modify the chassis to install this mount?

No chassis modification should be required if your model is listed as compatible; the mount is shaped to align with YZ-4 rear mounting points for direct replacement.

Any tips for aligning rear track during installation?

Install the mount and S4Arm-length arms loosely at first, measure wheel-to-wheel distance, then tighten progressively while confirming alignment to reach the desired rear track.

Will this change wheelbase or arm geometry?

The part is designed to preserve existing arm geometry; its purpose is to set the rear mounting surface so the wheelbase and geometry remain as intended when using S4Arm-length arms.

How should I verify compatibility before ordering?

Compare your car's B-series chassis code against the compatible models list shown above and confirm rear mounting point layout matches the YZ-4 pattern described in the product details.
