Metric Upper Control Arm Left 10in

The Metric Upper Control Arm Left 10in from ALLSTAR PERFORMANCE is a critical suspension component engineered for street, strip, and competition vehicles requiring precise front-end geometry and responsive handling characteristics. This left-side upper control arm serves as the foundation of modern suspension tuning, controlling wheel alignment, camber settings, and overall chassis dynamics. Whether you're building a drag racing machine, daily driver performance build, or competitive autocross platform, this control arm is essential for achieving repeatable, predictable steering response and tire contact optimization.

Engineered with metric specifications, this 10-inch control arm is designed to work seamlessly within modern suspension architectures where precise ball-joint angles and mounting geometry directly impact suspension travel, anti-dive characteristics, and roll stiffness distribution. The metric upper control arm's length and geometry control the instantaneous center of the front suspension, which determines how camber changes throughout the suspension stroke—a critical factor in maintaining consistent tire contact patch during cornering and acceleration events. Quality construction ensures repeatable performance across multiple sessions without deflection or geometry shift that could alter your tuning baseline.

This left-side control arm is ideal for mechanics and enthusiasts building independent front suspension systems on street performance vehicles, bracket racers dialing in launch geometry, or road racing platforms where suspension geometry consistency is non-negotiable. Installation requires proper ball-joint pressing equipment and alignment verification post-installation to ensure camber, caster, and toe specifications are within factory or tuning parameters. At 4.37 lbs, the compact design fits standard automotive suspension packaging while maintaining the structural rigidity demanded by aggressive driving disciplines.
