8-1/2in Upper A Arm Slotted 15 Degrees

The 8-1/2in Upper A Arm Slotted 15 Degrees by HOWE is a precision fabricated suspension component engineered for serious suspension geometry tuning and drag racing applications. This slotted upper control arm allows you to dial in camber adjustment on the fly without removing fasteners, making it ideal for competitive vehicles where fine-tuning alignment between rounds is critical. Built for racers and high-performance enthusiasts who demand adjustability, this upper A arm eliminates guesswork and saves valuable time in the pits.

The 15-degree slot geometry provides substantial camber range while maintaining structural integrity under load, a hallmark of HOWE's racing-focused design. The slotted mounting holes allow horizontal adjustment relative to the ball joint, enabling zero-offset or negative camber settings without wheel relocation or binding. Weighing just 4.7 lbs, this component is light enough for street or strip use, and the precision machining ensures consistent geometry repeatability across multiple adjustments. The 8-1/2-inch length positions it as a direct fit for mid-sized independent front suspension systems common in muscle cars and drag platforms.

This upper A arm suits bracket racers, street rod builders, and circle track competitors who need adjustability without fabrication. Installation typically pairs with a compatible lower control arm and requires basic alignment equipment and torque specs suited to your chassis. Verify fitment against your vehicle's spindle mounting face and frame pickup points before ordering; HOWE upper A arms are platform-specific. The slotted design works seamlessly with adjustable strut rods and panhard bars to dial in complete front-end geometry for optimal traction and handling.
