Radius Rod 5/8in Alum 14-1/2in

The Radius Rod 5/8in Alum 14-1/2in from ALLSTAR PERFORMANCE is a precision suspension component engineered for racers and street machine builders who demand reliability under load. Radius rods are critical lateral locating arms that control rear axle movement during acceleration, braking, and cornering—preventing bind-up and maintaining wheel alignment geometry. This aluminum construction delivers the strength needed for high-performance driving while minimizing unsprung weight, a key factor in improving suspension responsiveness and handling consistency on road courses, drag strips, and street applications.

Built from aluminum alloy, this 14.5-inch radius rod provides a lighter alternative to steel designs without sacrificing structural integrity. The 5/8-inch diameter rod offers optimal stiffness-to-weight ratio, resisting flex while keeping overall system mass low. ALLSTAR PERFORMANCE's engineering ensures precise hole alignment and consistent tolerances across both ends, enabling bolt-in installation to existing frame and axle brackets. The compact 1.2 x 1.2 x 14.6-inch profile makes it suitable for tight suspension setups where clearance is limited, and the 0.61-pound weight contributes minimal rotational inertia to your suspension assembly.

This radius rod works best in independent rear suspension systems, four-link rear suspensions, or modern muscle car platforms where lateral control arms manage axle tracking. Hot rod builders, performance enthusiasts, and drag racers benefit most from upgrading to aluminum construction when upgrading suspension geometry or increasing power output. Installation requires standard fabrication skills and basic hand tools; alignment checks post-installation ensure optimal suspension geometry. Whether you're tuning a street car for corner carving or building a competition rig, ALLSTAR PERFORMANCE's radius rod delivers the precision locating geometry serious builders depend on for predictable handling and durability.
