Kyosho MB018 Mini-Z Buggy Pillow Ball Set - Compact Ball-Joint Upgrade  [KY-MB018]

Compact ball-joint upgrade for Mini-Z

This pillow ball set is supplied as an RC replacement component tailored to Mini-Z Buggy platforms. It offers a space-saving ball-joint interface between steering links and suspension arms to preserve articulation while lowering unwanted clearance that harms precision on tight off-road courses.

Compatibility is limited to Mini-Z Buggy configurations; check your chassis details before purchase. The item takes the place of standard pivot or clevis fittings where pillow ball joints are used to improve repeatability in suspension motion and steering response.

Installation notes: remove existing linkage hardware and fit the pillow balls into the prepared link ends or hub locations provided by the chassis, using the original screw points. Verify smooth movement through the whole travel, do not overtighten which may bind the joint, and ensure no interference occurs during suspension compression.

Tuning role: installing pillow balls changes the effective pivot and can sharpen steering response while promoting consistent camber under load. Use this upgrade when you need less play at the steering knuckle and suspension connections, and retune roll center, damping, and toe to match.
