A-Arm 9.5in Screw-In B/J

The A-Arm 9.5in Screw-In B/J from JOES RACING PRODUCTS is a precision tubular control arm engineered for high-performance suspension systems where adjustability and durability are non-negotiable. Designed as an upper control arm with a 10-degree geometry, this component is purpose-built for vehicles requiring fine-tuned suspension geometry and reliable load management. Control arms are critical to maintaining proper wheel alignment, suspension travel, and vehicle stability during dynamic driving conditions—making quality construction and accurate specifications essential for both track and tactical vehicle applications.

Constructed from aluminum and steel with a protective black powder coat finish, the A-Arm 9.5in Screw-In B/J features a screw-in ball joint design that provides secure articulation and simplified field replacement when needed. The standard bushing style accommodates traditional suspension mounting while the 9.5-inch length is optimized for specific suspension geometries and ride heights. The tubular construction minimizes weight while maintaining structural rigidity, and the dual-material composition balances strength where it matters most—critical for maintaining suspension response under load and rough terrain. The black powder coat protects against corrosion and environmental degradation, ensuring longevity in harsh operational or racing environments.

Operators and builders of performance suspension systems—including military support personnel, off-road specialists, and racing teams—rely on this control arm for precise geometry maintenance and durability under extreme conditions. The screw-in ball joint design allows for quick removal and replacement without specialized press equipment, reducing downtime during field maintenance or component swaps. Proper installation requires verification of suspension geometry and alignment specifications for your specific platform; consult your vehicle's suspension documentation or a qualified technician to ensure correct fitment and performance. Weighing 3.5 lbs and measuring 12.95 x 1.7 x 13.95 inches, this control arm integrates into suspension systems where the 10-degree angle geometry is specified by your OEM or performance engineering parameters.
