Rod End - 5/8in x 5/8in RH Steel - Female

The QA1 Rod End - 5/8in x 5/8in RH Steel - Female is a precision spherical joint engineered for suspension geometry and steering linkage applications in performance and race vehicles. This right-hand female threaded rod end connects control arms, tie rods, and adjustable suspension components with smooth articulation and zero bind—critical for maintaining accurate alignment and consistent handling response under cornering loads. Whether you're building a street performance car, road course competitor, or off-road rig, this rod end delivers the adjustability and durability that separates purpose-built suspension from factory compromises.

Constructed from hardened steel with zinc oxide plating, the CFR10 features a 5/8-inch bore with matching 5/8-18 right-hand female thread geometry that ensures repeatable installation and secure engagement with standard threaded studs. The CF-series spherical design allows full range-of-motion in all directions while maintaining a compact 3.95-inch overall length and light 0.44-pound weight—minimizing unsprung mass without sacrificing load capacity. The polished ball joint interface rolls smoothly across its contact surface, reducing friction and noise compared to worn OEM bushings while enabling multiple adjustment angles for fine-tuning suspension geometry and ride height.

Mechanics and fabricators favor QA1 rod ends for custom A-arm fabrication, drag racing builds, and corner-weighted race cars where adjustability and precision matter. Installation requires basic threading onto your control arm or tie-rod tube—verify thread direction (right-hand) before torquing to specification. This rod end pairs seamlessly with adjustable control arms and tie-rod kits from leading suspension manufacturers, making it ideal for full-independent front suspensions and heavily modified rear-end conversions on classic and modern platforms alike.
