A-Arm 10.5in 20deg Screw In B/J Slotted Bearing

The A-Arm 10.5in 20deg Screw In B/J Slotted Bearing from JOES RACING PRODUCTS is purpose-built for high-performance marine applications where precision suspension geometry directly impacts handling, stability, and on-water performance. Whether you're running a performance boat, race vessel, or demanding offshore platform, this A-arm assembly delivers the geometry and bearing quality required to maintain consistent steering response and suspension articulation under sustained load and acceleration. JOES RACING has engineered this component for boaters and marine technicians who understand that suspension geometry—like the 20-degree angle and bearing design in this model—translates directly to predictable handling characteristics and durability.

The 10.5-inch A-arm with 20-degree geometry is designed to optimize suspension travel and steering radius for marine hull dynamics, reducing bind and ensuring smooth articulation throughout the range of motion. The screw-in ball joint (B/J) connection uses slotted bearing technology to allow fine-tuning of preload and wear compensation without full replacement—a critical advantage for boaters operating in saltwater or high-utilization environments where bearing wear is cumulative. The slotted bearing design accommodates wear and adjustment, extending service intervals and reducing downtime between seasons. At 3.84 lbs, this assembly is engineered for weight-conscious applications where every pound affects fuel efficiency and dynamic performance on the water.

Performance boaters, marine suspension specialists, and offshore racing crews rely on JOES RACING A-arm assemblies for OEM replacement and upgrading aging or worn suspension geometry. Installation requires proper alignment tools and bearing preload setup to maximize the slotted bearing adjustment capability; consult your vessel's suspension specifications or a qualified marine technician to confirm fitment and correct orientation. This component is ideal for boats experiencing vague steering feel, excessive bearing play, or handling changes due to worn OEM A-arms. Proper installation and periodic inspection ensure years of reliable performance in demanding marine conditions.
