King Pin for Stub Axle Upper Pivot Applications SKU: QT409870

When your stub axle king pin wears out, steering becomes unpredictable and dangerous. Loose king pins cause wandering on the road, uneven tire wear, and that exhausting need to constantly correct your steering. This hardened steel upper pivot pin restores precise steering control and prevents further damage to expensive front axle components.

Why Precision Matters

• Heat-treated steel construction resists wear, bending, and fatigue under heavy loads
• Precision-machined bearing surface maintains proper alignment and reduces play
• Engineered to handle lateral steering forces and vertical implement weight transfer
• Direct replacement design eliminates fitment guesswork

King pin service requires proper tools and procedures for safe installation. Always inspect bushings, seals, and related steering components during replacement, as worn king pins typically indicate broader front-end wear. For tractors handling heavy implements or loader work, this isn't just a repair—it's essential for operator safety and equipment protection.
