Radius Rod 5/8in Alum 19-1/2in

The Radius Rod 5/8in Alum 19-1/2in from Allstar Performance is a precision suspension component engineered for custom hot rods, street machines, and high-performance vehicles requiring enhanced chassis control and geometry correction. This aluminum radius rod serves as a critical link in modern suspension setups, managing lateral forces and maintaining wheel alignment under acceleration, braking, and cornering loads. Whether you're building a classic car resto-mod or refining an existing suspension package, this radius rod delivers the locating precision that separates a well-tuned chassis from one that feels loose or unpredictable on the road.

Constructed from lightweight aluminum with a 1.125-inch outer diameter tube, this 19.5-inch radius rod minimizes unsprung mass while maintaining structural rigidity—a critical trade-off in suspension design. The polished aluminum finish resists corrosion and offers a professional appearance visible in engine bays or frame rails, while the 5/8-18 female threads provide a standardized connection point compatible with most aftermarket suspension kits and custom fabrication standards. The compact 0.86-pound weight makes this component ideal for weight-sensitive builds without sacrificing the strength needed to manage dynamic suspension loads.

This radius rod suits builders working with independent front suspension (IFS) conversions, aftermarket control arm systems, and four-link rear suspension architectures where precise wheel location is non-negotiable. Mechanics and fabricators favor Allstar Performance components for their consistent tolerances and repeatable fitment across multiple applications. Verify your suspension system's specific geometry and thread requirements before installation—the 5/8-18 female thread must match your frame brackets or control arm ends to ensure proper load transfer and predictable handling characteristics.
