Yokomo YZ-S4RW2 Aluminum rear shock body for Works'91 TeamSpec rear suspension upgrade  [YZ-S4RW2]

Rear shock body for Works'91 TeamSpec

This is an RC-scale aluminum rear shock body designed for the Works'91 TeamSpec lineup. The body length is longer than the Works'91 standard, providing additional stroke options at the rear that can be used when tuning for increased traction or different balance points.

Fitment is specific to the YZ-W91TS platform and also supports YZ-W91 chassis as listed, the part is intended as a direct replacement hop-up for the rear suspension assembly and does not include internal components such as pistons or shafts.

Installation is straightforward for hobbyists familiar with typical shock servicing, swapping the shock body changes available travel and preload range, which can affect rear-end grip and transient handling when combined with spring and oil changes.

Use this aluminum body when you need extra rear stroke range for setup experimentation; verify tolerance with your existing shock shafts and seals before final installation.
