5/8 Aluminum Radius Rod 41in Black 1in OD

The 5/8 aluminum radius rod 41in black 1in OD from MPD Racing is a precision-engineered suspension component designed for custom chassis builders, fabricators, and performance mechanics who demand reliability in high-stress suspension geometry applications. Radius rods (also called control arms or A-arms in certain configurations) are critical load-bearing elements that locate the axle relative to the chassis while managing lateral and longitudinal forces. This 41-inch aluminum construction is engineered for lightweight builds where reducing unsprung mass directly improves handling response, acceleration, and braking performance—making it ideal for drag racing, short-course off-road, and street-legal performance vehicles.

Manufactured from aluminum and finished in durable black anodize, the 5/8 aluminum radius rod features a 1-inch outer diameter (OD) tube with 5/8-18 female threads at both ends for secure fastening to rod ends, spherical joints, or clevis mounts. The 5/8-18 thread specification ensures compatibility with standard rod end hardware and allows precise length adjustment during suspension tuning. Black anodized aluminum provides corrosion resistance while maintaining a clean appearance, and the 1.35-pound weight contributes minimal mass to your suspension system—critical in weight-sensitive applications where every pound affects acceleration and handling balance. The 41-inch length accommodates mid-travel to long-travel suspension geometries common in performance and off-road platforms.

This radius rod is best suited for fabricators building custom chassis, performance enthusiasts upgrading independent suspension systems, and mechanics specializing in drag racing, rock crawling, or high-speed off-road rigs where OEM suspension geometry must be engineered for specific ride heights and anti-squat characteristics. Before installation, verify that the 41-inch length and 5/8-18 female threads match your suspension design and rod end specifications; consult your chassis blueprint or suspension schematic to confirm compatibility. MPD Racing's aluminum radius rods are engineered to withstand serious use—ensure proper heim joint selection and that all connections are torqued to specification for safety-critical suspension work.
