Quadboss 411150 ATV Ball Joint Kit Heavy-Duty Steel Replacement

The Quadboss 411150 is a heavy-duty replacement ball joint kit engineered for ATV suspension systems. Designed to address the shortcomings of factory components, this kit upgrades the standard OEM aluminum joint to a heavy-duty steel construction, delivering superior strength and longevity for demanding off-road riding conditions.

Key Features:

• Heavy-duty steel case provides greater strength than OEM aluminum joints found on many stock machines
• POM-M90 bearing cup isolates the ball end from the case, reducing friction and extending service life
• Sold per A-arm — kit includes the ball joint, snap ring, and cotter pin for a complete installation
• Direct OEM-style fitment for straightforward installation without modifications
• Meets or exceeds OEM specifications for fit, function, and performance
• Ideal replacement for applications that would otherwise require purchasing an entire A-arm or steering knuckle

Ball joints are a critical suspension component, connecting the control arm to the steering knuckle and enabling smooth up-and-down wheel travel while maintaining precise steering response. Worn ball joints can cause clunking noises, loose or wandering steering, and accelerated tire wear. The Quadboss 411150 restores proper suspension geometry and handling confidence for trail riders, ranchers, and off-road enthusiasts alike.
