Radius Rod 5/8in Alum 15in Black

The Radius Rod 5/8in Alum 15in Black from ALLSTAR PERFORMANCE is a precision suspension component engineered for high-performance vehicle builds and chassis tuning. Radius rods—also known as trailing arms or link tubes—are critical to controlling frame geometry and wheel alignment during acceleration, braking, and cornering. This 15-inch aluminum radius rod is designed for street rods, race cars, and modified vehicles where suspension geometry management directly impacts handling, traction, and overall performance. Whether you're building a vintage hot rod, competing in bracket racing, or fine-tuning a custom suspension setup, this component provides the strength and adjustability needed for serious suspension work.

Manufactured from aluminum and finished in black anodize, this radius rod features a 1.125-inch outside diameter tube with 5/8-18 female threads at both ends for secure fastening to frame mounts and suspension points. The aluminum construction keeps unsprung weight to a minimum—critical for independent front suspension or rear-end setups where reducing rotational and vertical mass improves response and reduces tire wear. At just 0.62 lbs, the 15-inch length suits compact to mid-size chassis modifications, making it ideal for Chevy S-10 builds, early-model street rods, or custom tube-frame race cars. The black anodized finish resists corrosion and provides a professional appearance while withstanding the demanding environment under a vehicle.

Mechanics and fabricators favor ALLSTAR PERFORMANCE radius rods for DIY suspension geometry correction and race-car setup optimization. Installation requires precision alignment during fastening to prevent bind and ensure smooth suspension travel; the 5/8-18 threads accept standard fasteners for quick adjustment of suspension angle. This component works best paired with control arms, sway bars, and properly tuned springs and shocks to achieve desired anti-squat, anti-dive, and roll characteristics. Verify frame-mount spacing and suspension layout before purchase to ensure the 15-inch length matches your specific application and geometry targets.
