Radius Rod 5/8in Alum 24in

The Radius Rod 5/8in Alum 24in from ALLSTAR PERFORMANCE is a precision-engineered suspension component designed for street rods, race cars, and custom vehicles requiring adjustable geometry control. Radius rods (also called control arms or trailing arms) manage chassis location and suspension travel by maintaining axle position relative to the frame while allowing vertical wheel movement. This 24-inch aluminum tube with 5/8-18 female threaded ends serves as the structural link between frame and rear axle, making it essential for vehicles with independent rear suspension setups or custom four-link systems where OEM components have been replaced or modified.

Constructed from lightweight aluminum, this radius rod features a 1.125-inch outer diameter tube with a polished finish that resists corrosion while maintaining a clean appearance in visible engine bays. The 5/8-18 female threads on both ends accept standard rod ends or spherical ball joints, allowing for quick adjustability and geometry tuning without welding. Aluminum construction reduces unsprung weight compared to steel alternatives, improving suspension response and reducing the rotational mass that must be controlled during acceleration and braking. The 24-inch length provides adequate geometry options for mid-engine and rear-engine builds, though custom fabricators often pair these tubes in multi-link configurations to fine-tune anti-squat, anti-dive, and roll center characteristics.

This component is ideal for hot rod builders, drag racers, and suspension tuners who demand adjustability and lightweight construction. It pairs seamlessly with rod end kits, spherical bearings, and adjustable coilover systems common in road race and autocross platforms. Installation requires proper alignment and geometry calculation—radius rod length and angle directly affect rear axle location, so measurement and adjustment during assembly are critical. Compatible with custom frame work, bolt-on suspension kits, and fabrication projects where OEM suspension geometry must be reconfigured for performance, lowering, or weight distribution goals.
