Radius Rod 5/8in Alum 19in Black

The Radius Rod 5/8in Alum 19in Black from ALLSTAR PERFORMANCE is a precision-engineered suspension component designed for serious chassis builders and performance mechanics who demand reliable geometry control. This aluminum suspension tube addresses a critical need in custom suspensions: maintaining accurate front-end geometry while accommodating adjustability for ride height and alignment tuning. Whether you're building a circle-track race car, a street rod, or a competition vehicle, this radius rod serves as the lateral locating member that controls anti-dive characteristics and suspension kinematics.

Constructed from lightweight aluminum with a 1.125-inch outer diameter tube, this 19-inch radius rod features 5/8-18 female threads machined into both ends for secure attachment to frame brackets and suspension pickup points. The black anodized finish provides corrosion resistance and a professional appearance while protecting against oxidation in harsh environments. The 0.83-pound weight keeps unsprung mass minimal—a critical consideration in performance vehicles where reducing suspension component weight improves ride quality, handling response, and brake performance. Aluminum construction delivers sufficient strength for most applications while maintaining the geometry adjustability that tuners require for corner-weight balancing and moment-center refinement.

This radius rod is essential for fabricators working with independent front suspensions, double-A-arm systems, and custom chassis builds where factory suspension geometry doesn't meet performance requirements. Installation requires mating the threaded ends to corresponding suspension brackets and frame mounts using appropriate fasteners and jam nuts for locking. The 19-inch length accommodates mid-size to full-size vehicle platforms; verify mounting center-to-center distances before ordering to ensure proper fit. Technicians should check suspension geometry using alignment equipment after installation to confirm anti-dive angles, roll center location, and bump steer characteristics match design specifications.
