Moose / All Balls Heavy‑Duty 12mm Tie‑Rod Assembly Upgrade Kit for Arctic Cat 250–500 & Suzuki KingQuad 400/500

OVERVIEW

Moose Racing’s Heavy‑Duty 12mm Tie‑Rod Assembly Upgrade Kit replaces flexible OEM steering linkages with a direct bolt‑on solution engineered to restore precise ATV handling. Moving from standard 10mm tie‑rod ends to reinforced 12mm assemblies eliminates chassis play and strengthens the steering system under rough terrain loads. Designed specifically for Arctic Cat 250–500 and Suzuki KingQuad 400/500 platforms, this hardware package delivers reliable power transfer control and long‑term durability for trail riding, utility work, or age‑related restorations.

ENGINEERING & PERFORMANCE

The transition from lightweight OEM 10mm ends to hardened 12mm tie‑rod shafts reduces steering flex and keeps the front suspension synchronized during sharp turns or heavy pulls. Constructed with heavy‑duty metallurgy and precision‑threaded joints, the assembly resists shock absorption damage, corrosion buildup, and premature joint fatigue. The drop‑in design preserves factory steering ratios while tightening the feedback loop between handlebars and wheels. Every mounting interface matches original bracket spacing, allowing technicians to bypass alignment checks and return machines to service faster.

KEY FEATURES

• Upgrades fragile OEM 10mm tie‑rod ends to robust 12mm heavy‑duty assemblies
• Kit includes two complete tie‑rods and four matched tie‑rod ends
• Addition of high‑grade cotter pins and thread‑locking jam nuts for secure adjustment
• Direct bolt‑on replacement requiring zero bracket modification or welding
• Reinforced linkage architecture minimizes wheel wander and steering backlash
• Tailored for Arctic Cat and Suzuki mid‑size ATV steering racks

WHY RIDERS CHOOSE THIS

Riders install this kit when stock tie‑rods begin to flex under cornering loads, causing vague steering feedback and accelerated wear at the knuckle joints. The 12mm heavy‑duty shafts and reinforced bushing pockets lock the steering axis into a tighter tolerance, delivering punchier turn‑in response and stable straight‑line tracking over roots, ruts, and rock gardens. Because the hardware mounts directly to factory brackets without drilling or trimming, mechanics save labor hours while preserving original suspension kinematics. It serves as a durable, cost‑effective reinforcement that prevents early linkage failure on both weekend trail rigs and daily work ATVs.
