10.75in Upper A Arm Slotted 15 Degree

The 10.75in Upper A Arm Slotted 15 Degree from HOWE is purpose-built for serious suspension tuners and bracket racers who demand precision geometry control in their vehicles. This upper control arm is engineered for applications where adjustable camber and caster settings are critical to cornering performance, weight transfer management, and tire wear optimization. Whether you're dialing in a street machine, autocross competitor, or drag racing platform, this component gives you the fine-tuning capability that separates competitive builds from stock-limited setups.

The slotted design is the key to this arm's versatility—multiple mounting positions allow you to adjust the angle of attack without fabricating custom brackets or dealing with fixed geometry limitations. The 15-degree angle specification provides a geometry baseline suitable for aggressive cornering work while maintaining drivability on public roads. At 5 pounds, the arm is light enough to reduce unsprung weight without sacrificing rigidity, and HOWE's meticulous manufacturing ensures the ball joints seat cleanly and the mounting eyes remain perfectly aligned under load. The 10.75-inch length fits popular street and competition chassis where wheel travel and clearance matter.

Installers upgrading vintage muscle cars, Pro Street builds, or modern performance platforms benefit most from this adjustable upper control arm. Before fitting, confirm your vehicle's spindle bore diameter and ball joint taper angle match HOWE's specifications for your chassis. Installation typically requires a spring compressor and suspension alignment afterward—treat geometry changes with a full corner weight and alignment session to lock in camber, caster, and toe values. This is a core suspension component for builders serious about handling envelope optimization.
