Moose / All Balls Steering Rack Assembly Replaces 391910022 for Kawasaki Mule SX / 610 / 600 (KAF400)

OVERVIEW

Restore precise directional control and eliminate unsafe steering play with this direct‑replacement Steering Rack Assembly. Designed specifically for Kawasaki KAF400 platforms, this unit combines a durable rack housing, both inner tie‑rod ends, and dual tie‑rods into a single repair kit. Built using heavy duty industrial standards, it serves as a reliable upgrade for daily utility vehicles, agricultural work machines, and recreational models that require consistent front end reliability.

ENGINEERING & PERFORMANCE

The complete assembly transfers steering input directly to the wheels with minimal friction, effectively clearing binding and excessive clearance found in worn units. Engineered with reinforced housings and precision‑machined mounting surfaces, the hardware resists deformation under constant front end load and heavy ground contact. The integrated tie rod linkage maintains proper alignment across the full operating range, while the direct bolt configuration ensures immediate return to factory handling characteristics without fabrication or alignment jigs.

WHY RIDERS CHOOSE THIS

Operators working in agriculture and maintenance environments select this steering rack assembly because it completely addresses front end wear rather than requiring partial repairs. The unified kit design eliminates multiple failure points by replacing the worn rack housing alongside both tie rod ends and linkages simultaneously. Heavy duty manufacturing tolerances maintain consistent streetable clearance and prevent vibration transfer back through the cab during rough terrain operation. Mounted directly to existing bracketry, this replacement restores exact factory steering geometry and delivers predictable handling for demanding daily shifts.
