Overview of the YZ-4 rear RR mount

This aluminum rear suspension mount is the right-rear replacement piece engineered for the Yokomo YZ-4 scale touring chassis. It is machined to sit at the chassis rear and is intended for use with S4Arm-length suspension arms so the rear track aligns with required widths.

Install this mount when you require a precise rear mounting surface to control track width and alignment without altering the arm geometry. The product is supplied as a bare mount to fit YZ-4 rear mounting points; check the compatibility list below to ensure your B-series chassis is supported.

How durable is this machined aluminum mount in everyday use?

Machined aluminum offers a stiff mounting surface that resists deformation under normal racing loads, helping maintain rear alignment session to session.

Can this mount influence handling characteristics?

By locking in a precise rear track, the mount can affect transient handling and balance; small track adjustments change grip distribution and rear-end behavior during cornering.

Is additional machining or finishing required before fitting?

The mount is supplied machined and ready to fit; inspect mating surfaces and remove any burrs if present, but no further machining is normally necessary.

Will this work with aftermarket arm variants?

It is designed for use with S4Arm-length suspension arms; verify arm length and mounting hole spacing on aftermarket arms to ensure correct fitment before installation.
