Rear upper arm mount for YZ-4

This is the standard rear upper arm mount designed for the 1/10 4WD off-road YZ-4 platform. The part positions the upper end of the rear suspension arm and works with the existing rear suspension geometry of the YZ-4.

The mount includes a caster-adjustment bush that provides selectable caster angles at 0°, 2.5° and 5°. Changing the bush alters rear axle inclination relative to the hub, allowing straightforward tuning of steering return and high-speed stability without replacing the suspension arm.

Installation follows the YZ-4 rear mounting points and uses the original chassis hardware, no modification to the chassis is required. Keep fasteners torqued to match the original setup and verify clearance after fitting.
