Clevis - 3/8in Bore x 5/8in Thread

The QA1 Clevis - 3/8in Bore x 5/8in Thread is a precision rod end assembly engineered for performance suspension and steering linkage applications in modified vehicles, race cars, and custom builds. This clevis-style rod end serves as the critical connection point between control arms, tie rods, and other suspension components, allowing for proper articulation while maintaining structural integrity under dynamic loads. Whether you're upgrading a street machine, building a dedicated track car, or refining suspension geometry on a high-performance platform, this component provides the adjustability and durability serious enthusiasts demand.

Manufactured from quality steel in natural finish, the QA1 clevis features a 3/8-inch bore for ball joint or bearing installation and a 5/8-18 right-hand male thread for secure mounting into chassis brackets or suspension arms. The clevis design—with its forked geometry—distributes loads evenly across the pin hole and threaded section, reducing stress concentration compared to standard rod ends. At just 0.325 lbs, this compact assembly (2.8 x 0.95 x 4.25 inches) integrates seamlessly into tight suspension packages while maintaining the rigidity required for responsive handling and consistent alignment under cornering and braking forces.

Custom suspension builders and performance shops rely on QA1 rod ends for independent front suspension (IFS) upgrades, A-arm fabrication, and adjustable steering linkage tuning. The 5/8-18 thread is a common specification across chassis tubes and brackets, making this clevis a go-to choice for bolt-together and welded suspension frames alike. Installation requires a properly sized clevis pin or bolt through the 3/8-inch bore; verify bore diameter compatibility with your pin or bushing before assembly. This component pairs well with other QA1 suspension products and aftermarket control arm kits designed for vehicles ranging from vintage hot rods to modern performance platforms.
