5/8 Aluminum Radius Rod 25in Plain 1.125 OD

The 5/8 Aluminum Radius Rod 25in Plain 1.125 OD by Ti22 Performance is a precision-engineered suspension component designed for custom vehicle builders, fabricators, and performance mechanics who demand adjustability in chassis geometry and suspension kinematics. Radius rods control the geometry of independent suspension systems—dictating anti-squat, anti-dive, and pinion angle geometry—making them essential for tuning handling characteristics on drag cars, road course builds, and high-performance street vehicles. This aluminum tube delivers the lightweight advantage critical for weight-sensitive performance applications while maintaining structural rigidity required for suspension loads.

Constructed from aerospace-grade aluminum, the 1.125-inch outer diameter tube provides an optimal balance between strength-to-weight ratio and bending stiffness for mid-size radius rod applications. The 5/8-18 female threads on both ends accept standard rod ends and clevis fittings, allowing for adjustable length configurations and precise suspension geometry tuning. At 25 inches long with a plain (unpolished) finish, this radius rod integrates seamlessly into custom-fabricated independent rear suspension (IRS), A-arm, or multi-link suspension systems where adjustability is paramount for dial-in and track optimization.

Fabricators and suspension tuners benefit most from this component when building adjustable rear suspensions on tube-frame drag cars, vintage muscle car restorations with modern IRS conversions, or road racing platforms requiring geometry refinement. The lightweight aluminum construction reduces unsprung weight compared to steel alternatives, improving acceleration and braking response while lowering the vehicle's center of gravity. Installation requires basic rod end and clevis hardware (sold separately); measurement and fitting should account for the specific geometry of your suspension design to ensure proper anti-squat and anti-dive angles.
