Upper A Arm 10.5 Steel Ball Joint Plate Style

The Upper A Arm 10.5 Steel Ball Joint Plate Style by U-B MACHINE is a precision suspension component engineered for heavy-duty tactical and off-road vehicle platforms. This upper control arm is designed for operators and technicians who demand uncompromising durability in extreme-use environments—from law enforcement pursuits to military field operations. The 10.5-inch configuration provides optimal geometry for vehicles requiring enhanced articulation and load stability under combat or high-stress conditions.

Constructed from hardened steel and finished with a ball joint plate design, this component delivers superior rigidity compared to cast alternatives while maintaining precise steering geometry. The steel construction resists shock loads, corrosion, and the thermal stress inherent to sustained tactical operations. At 3.57 pounds, the arm balances structural integrity with weight efficiency—critical factors in vehicles where every pound affects mobility, fuel economy, and suspension response. The ball joint configuration allows smooth articulation across extreme suspension travel, essential for rough-terrain egress and dynamic driving demands.

This upper A arm benefits technicians servicing high-performance trucks and SUVs used in tactical, law enforcement, and military applications. Installation requires proper alignment procedures to maintain vehicle handling characteristics and tire wear patterns. The 10.5-inch length suits mid-size platforms with independent front suspension geometry; always verify compatibility with your specific year, make, and model before ordering. Replacement of worn suspension components restores original steering response and eliminates dangerous play in the steering column.
