YZ-4 Resin Suspension Mounts Front Upper & Rear Lower - Z4-300 Yokomo  [Z4-300]

Resin front upper and rear mounts for YZ-4

This kit supplies resin front upper arm mounts and rear lower suspension mounts as direct replacements for the YZ-4 4WD off-road buggy. These components are for RC use only and act as service or spare parts during suspension maintenance or setup changes.

Use notes:

• Material: resin, suited to routine repair and light tuning tasks where original plastic parts are swapped out.
• Function: maintains arm pivot locations and suspension mounting geometry, influencing roll center and overall suspension feel during setup changes.
• Fitment: produced for the YZ-4 family with reference to the B-YZ4 chassis; always verify physical fit against your current mounts before final installation.

Installation guidance: these mounts replace the factory front upper and rear lower suspension mounting points and generally accept the original hardware and hinge pins. Inspect fasteners and bearings for wear and remove any excess play at pivots before completing assembly.

Compatibility: Compatible with YZ-4, supported chassis B-YZ4 as referenced.
