YZ-4 Front Rear Suspension Spacer Set - Yokomo Z4-300RFS  [Z4-300RFS]

Front-side spacer for YZ-4 rear suspension

This spacer set fits the front side of the rear suspension mount on the YZ-4 chassis and is supplied as a replacement or upgrade accessory for RC-scale tuning. The components act as spacing shims that alter clearance at the mount point, allowing subtle changes to how the rear suspension sits relative to the chassis.

Installation is straightforward: place the spacers at the front-facing location of the rear suspension mount where the existing mounting hardware retains them. The set is designed to work with the original mount assembly; after fitting, always check that the spacers are seated securely and that suspension links move freely.

As a setup item the spacer set is a minor geometry tool rather than a primary suspension element. Varying spacer thickness or stack count changes effective mount spacing and can affect rear roll behavior, preload and the initial pivot location; make small steps and test on-track to assess results.
