Rod End - Special 5/8in Bore 9/16-18 Right Thrd

The QA1 Rod End – Special 5/8in Bore 9/16-18 Right Thread is a precision-engineered spherical rod end bearing designed for high-performance suspension and drivetrain applications. This component serves as a critical pivot point in custom suspension geometry, allowing articulation between control arms, tie rods, and linkage components while maintaining load capacity and alignment precision. Rod ends are essential for builders who demand adjustable suspension geometry, whether tuning a track-focused street rod, competition drag car, or high-performance street machine where factory bushings lack the precision or adjustability required.

This QA1 rod end features a 5/8-inch bore diameter with a 9/16-18 right-hand thread, engineered for direct installation into custom-fabricated suspension brackets or OEM pickup points modified for adjustable geometry. The spherical ball joint design allows full articulation in all planes, critical for maintaining constant suspension angles during aggressive cornering or suspension travel. QA1's precision manufacturing ensures minimal play and consistent feel throughout the suspension range, with hardened steel construction rated for repeated high-load cycles. The right-hand thread orientation suits standard suspension linkage geometry, simplifying installation on driver-side and front-biased suspension layouts common in street rods and performance builds.

This rod end is ideal for builders fabricating custom A-arms, panhard bars, track-link assemblies, or adjustable suspension geometries where repeatability and precision matter. Weighing just 0.49 lbs, it minimizes unsprung weight while delivering durability across thousands of miles of street driving or race applications. Installation requires proper bore sizing and hardware selection; the 5/8-inch bore accepts standard 5/8-inch bolts or rod ends, while the 9/16-18 threaded stud connects directly to fabricated brackets or existing suspension mounting points. Compatible with most suspension-tuning applications where adjustable geometry enhances handling balance or accommodates engine/chassis combinations requiring modified suspension angles.
