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

The Rod End - 5/8in x 5/8in RH Chromoly - Female from QA1 is a precision spherical rod end engineered for high-performance suspension and chassis applications where angular misalignment must be accommodated without binding or wear. This female-threaded component serves as a critical pivot point in control arms, tie rods, and adjustable linkage systems where durability and smooth articulation are non-negotiable. Whether you're building a street machine, competition suspension, or restoring a classic with modern geometry, this rod end delivers the controlled movement and load capacity that separates amateur builds from professional installations.

Constructed from chromoly steel with a zinc-oxide finish, the QA1 XFR10 features a PTFE-lined spherical bearing that eliminates metal-to-metal contact and enables frictionless rotation through multiple planes of movement. The 5/8-inch bore and 5/8-18 right-hand female thread provide ample load capacity while maintaining compatibility with standard suspension component sizing. PTFE (polytetrafluoroethylene) lining reduces friction, extends bearing life, and minimizes the need for frequent lubrication—a critical advantage in sealed suspension designs where grease retention is difficult. The chromoly construction resists fatigue cracking under cyclic suspension loading, while the zinc-oxide coating provides corrosion protection for long-term reliability in both street and track environments.

Fabricators and chassis builders rely on QA1 rod ends to maintain precise suspension geometry without deflection or play that compromises handling. The right-hand thread designation ensures proper fastening direction and prevents accidental loosening under suspension cycling. Installation requires a properly sized adjuster or tie rod body with matching 5/8-18 female thread; verify thread pitch and bore diameter before purchase to ensure seamless integration. At 0.47 lbs, this compact rod end fits tight suspension packages while delivering the strength required for independent rear suspension, A-arm linkage, and steering correction systems on vehicles ranging from street rods to competition builds.
