A-Arm Shaft Steel Bushing Style Slotted

The A-Arm Shaft Steel Bushing Style Slotted control arm cross shaft from JOES RACING PRODUCTS (MPN 15040) is engineered for racers and performance enthusiasts who demand precise suspension geometry and durability in high-stress driving environments. Control arm cross shafts serve as the critical pivot point connecting your A-arms to the chassis, and upgrading to a purpose-built racing version eliminates the compliance and wear inherent in stock designs. This slotted bearing-style construction is designed for independent suspension systems where adjustability and load capacity directly impact lap times, handling balance, and long-term reliability on both track and street applications.

Built from steel and manufactured to JOES RACING PRODUCTS' exacting standards, this cross shaft features a slotted design that accommodates bearing-style bushings, allowing for smooth articulation while maintaining rigidity under cornering loads. The slotted configuration provides fine-tuning capability for suspension alignment, enabling mechanics to dial in caster, camber, and ride height with precision unmatched by welded or pinned alternatives. At 14.05 inches in length with compact 2.85 x 1.4-inch width dimensions, this shaft integrates cleanly into space-constrained chassis layouts while the 2.59 lb weight keeps unsprung mass minimal—critical for acceleration response and suspension compliance at the limits.

This universal A-arm cross shaft is ideal for custom chassis builds, circle track racing, road course competition, and street rod projects where OEM suspension geometry cannot meet performance requirements. Installation requires compatible bearings and bushings sized to fit the slotted design, along with proper torque specifications to prevent loosening under acceleration and braking loads. Verify your A-arm bore diameter and shaft mounting configuration before purchase to ensure correct fitment; consult your chassis builder or suspension engineer for specific compatibility requirements with your vehicle's control arm design.
