8-1/4in Upper A-Arm Slotted 15 Degrees

The HOWE 8-1/4in Upper A-Arm Slotted 15 Degrees (Model 2213315) is a precision tubular control arm engineered for high-performance suspension geometry adjustment. This upper A-arm features screw-in ball joint construction with 8.25-inch length specification, delivering repeatable control arm angles critical for chassis setup and weight transfer optimization in competition and off-road applications.

The 15-degree slot configuration allows fine-tuning of suspension geometry without requiring complete arm replacement, reducing setup time between runs and lowering total component costs. Built from steel construction with blue powder coat protection, this arm resists corrosion while maintaining precise bore tolerances required for ball joint installation. The slotted design enables incremental angle adjustments that directly influence camber, caster, and anti-dive characteristics—variables that experienced chassis builders prioritize when dialing in handling balance across varying track conditions or terrain.

This component is designed for builders and technicians who understand suspension fundamentals and require a versatile control arm solution for custom chassis applications. The universal fitment designation indicates compatibility across multiple platform builds, making this HOWE upper A-arm a practical choice for those standardizing on proven suspension components. Each arm ships as a single unit, allowing modular suspension assembly and incremental system upgrades.

HOWE has established a reputation in motorsports suspension for holding tight tolerances and manufacturing consistent geometry in slotted and adjustable control arms. The 8.25-inch length specification places this arm in the standard range for mid-sized chassis platforms, making it a benchmark reference for suspension geometry shops and fabricators evaluating control arm options for performance builds.
