Radius Rod 5/8in Alum 24in Black

The Radius Rod 5/8in Alum 24in Black from ALLSTAR PERFORMANCE is a precision suspension control component engineered for street rods, custom hot rods, and modern muscle cars where geometry and handling tuning demand adjustable locating arms. Radius rods—also called longitudinal control arms—control axle wrap and wheel hop while maintaining lateral wheel position during acceleration and braking events. Whether you're building a dedicated drag car, restoring a classic with modern suspension geometry, or fine-tuning a daily-driven performance vehicle, this 24-inch aluminum radius rod provides the adjustability and durability required to dial in chassis dynamics without the weight penalty of traditional steel alternatives.

Constructed from aluminum alloy, this 5/8-inch diameter rod delivers structural rigidity while weighing just 1.15 pounds—a significant advantage in weight-critical builds where unsprung mass reduction improves suspension response and tire contact. The 24-inch length accommodates mid-travel and long-travel rear suspension setups common in custom street rods and modern drag-focused platforms. Aluminum construction also resists corrosion compared to bare steel, reducing maintenance in both street and track environments. The black powder-coat finish provides durable protection against UV degradation and road salt exposure while maintaining a professional appearance under the vehicle.

Professional fabricators and enthusiast mechanics install radius rods on independent rear suspension systems, 4-link and triangulated 3-link rear suspension setups, and modified live-axle platforms where bolt-on adjustable locating arms aren't available or sufficient. The 1.25 x 1.25-inch cross-section provides adequate stiffness for high-load acceleration and braking cycles while remaining light enough for street applications. Pair this radius rod with spherical rod ends and adjustable mounts to achieve geometry correction for lowered ride heights, wheelie bars, or custom axle centerline positioning. Installation requires welding or fastening to existing frame or suspension members—consult your suspension designer or shop manual for mounting location and angle specifications specific to your vehicle platform.
