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

The QA1 Rod End - 5/8in x 5/8in RH Chromoly - Male is a precision spherical bearing component engineered for high-performance suspension systems, drag racing builds, and street rod fabrication. This rod end connects control arms, tie rods, and steering linkage to steering knuckles and suspension mounting points, allowing articulation while maintaining structural rigidity. Whether you're building a competition suspension geometry or restoring a classic hot rod, a quality chromoly rod end is essential for repeatable handling, reduced deflection under load, and extended component lifespan.

Constructed from chromoly steel with black oxide finish, this QA1 PCM Series rod end features a 5/8-inch bore on both the threaded and clevis ends, with a right-hand male thread for secure installation into female-threaded suspension components. The spherical design allows ±10–15 degrees of angular movement, compensating for suspension geometry changes during compression and extension cycles without binding. Black oxide coating provides corrosion resistance and a clean finished appearance, while chromoly material offers superior strength-to-weight ratio compared to standard mild steel, critical in high-G cornering and acceleration environments where suspension loads exceed 2,000 lbs per corner on performance vehicles.

This rod end is ideal for fabricators, race teams, and suspension tuners working on A-arm brackets, panhard bar mounts, and adjustable control arm setups on street rods, circle-track racers, and modern performance cars with custom independent suspension systems. The 5/8-inch diameter bore accepts standard chromoly rod bushings and needle bearings, ensuring compatibility with most aftermarket suspension kits and custom fabrication mounts. Installation requires torquing the threaded end into a properly-sized female helix (typically aluminum or ductile iron) while allowing the spherical joint to articulate freely—do not over-tighten, as this restricts ball movement and accelerates wear. Each rod end ships individually, allowing builders to source complete suspension linkage sets from a single supplier.
