Rod End - 5/8in x 5/8in RH Aluminum - Male

The QA1 Rod End - 5/8in x 5/8in RH Aluminum - Male is a precision spherical bearing assembly engineered for high-performance suspension and steering linkage applications. This component serves as the critical connection point between control arms, tie rods, and drag links in custom and race-oriented vehicles where durability and adjustability are non-negotiable. Whether you're building a competition suspension system or upgrading a street performance platform, this aluminum rod end delivers the precision fit and movement tolerance that modern chassis dynamics demand.

Built from lightweight aluminum and finished in red anodize for corrosion resistance, the QA1 AMR10 features a 5/8-inch bore with matching 5/8-18 right-hand male thread—a standard size across domestic and import chassis modifications. The spherical bearing design allows full articulation without binding, while the PTFE (polytetrafluoroethylene) liner provides low-friction movement and extended service life under load cycling. The right-hand male thread configuration ensures compatibility with standard threaded adjustable control arm tubes and end-link applications, enabling fine-tuning of suspension geometry and ride height. At just 0.22 lbs, the aluminum construction reduces unsprung weight—a critical factor in handling responsiveness and acceleration performance.

Mechanics and fabricators building custom A-arm assemblies, adjustable suspension kits, or performance steering components rely on QA1 rod ends for their proven track record in road course, drag racing, and street performance environments. The PTFE lining reduces noise and vibration transfer compared to sealed rubber alternatives, making these ideal for vehicles where suspension feedback and steering response matter. Installation requires standard threading into prepared aluminum or steel tube ends; ensure proper alignment and torque specifications for your specific application to maximize bearing longevity and chassis stability.
