11-1/4in Upper A Arm Slotted 0 Degrees

The 11-1/4in Upper A Arm Slotted 0 Degrees from HOWE represents a critical suspension upgrade for serious racers and high-performance vehicle builders. Upper A-arms are fundamental to chassis geometry, controlling wheel alignment, camber curves, and steering response throughout suspension travel. The slotted design with 0-degree geometry allows fine-tuning of front-end alignment without requiring complete arm replacement, making this component essential for circle track racing, road course competition, and drag racing applications where precise geometry tuning directly impacts lap times and consistency.

HOWE's manufacturing expertise delivers a precision-engineered upper A-arm built from high-strength materials engineered to withstand the lateral forces and shock loads inherent in competitive motorsports. The slotted ball joint mounting allows adjustment of camber curves and roll center without purchasing multiple arms—a significant advantage when dialing in setup across different track conditions. At 5.1 lbs, this component maintains a lightweight profile critical to minimizing unsprung weight, which directly improves suspension response and brake performance. The 11-1/4-inch length and 0-degree initial geometry specification are designed to work with standard double-A-arm suspension systems common in circle track and road racing platforms.

This upper A-arm suits racers who demand adjustability without fabrication work—teams running multiple cars, frequent setup changes, or competitive series with strict OEM-based rules benefit most from slotted designs. Installation requires basic suspension knowledge and proper alignment equipment; improper geometry settings will negatively affect handling and tire wear. Compatibility depends on your specific frame and suspension system design, so confirm mounting dimensions and ball joint specifications with your chassis builder or suspension supplier before ordering. Serious competitors and suspension-focused shops trust HOWE for repeatability and precision that translates to measurable on-track performance gains.
