Radius Rod 5/8in Alum 18-1/2in

The Radius Rod 5/8in Alum 18-1/2in from ALLSTAR PERFORMANCE is a precision-engineered suspension tube designed for custom chassis and performance vehicle builds. This component serves as a critical bracing element in independent front suspension systems, controlling geometry and reducing unwanted lateral movement during acceleration, cornering, and load transfer. Whether you're fabricating a race car, hot rod, or high-performance street machine, this aluminum radius rod provides the structural support and adjustability needed for fine-tuned suspension kinematics.

Manufactured from aluminum and finished to a polished specification, this radius rod features a 1.125-inch outer diameter tube with 5/8-18 inch female threads at one end, allowing secure attachment to frame mounts or control arm brackets. The 18.5-inch length accommodates a wide range of chassis configurations and suspension setups, while the lightweight aluminum construction reduces unsprung mass compared to steel alternatives—a critical advantage in performance applications where reduced rotational inertia improves handling response and tire contact consistency. The polished finish resists corrosion and provides a professional appearance suitable for show-quality builds.

Builders and fabricators working on custom A-arm suspensions, ladder-bar setups, or geometric adjustments will find this component essential for achieving precise suspension alignment and anti-squat characteristics. Installation requires mating the 5/8-18 female threads to appropriately sized male fasteners or rod ends, making it compatible with standard rod end assemblies and frame brackets. Commonly used in street rods, circle track cars, and high-end custom builds, the Radius Rod 5/8in Alum 18-1/2in delivers the dimensional precision and material quality that serious fabricators expect for long-term reliability and adjustability in competitive or show environments.
