Rod End - 5/8in x 5/8in LH Steel - Male

The QA1 rod end 5/8in x 5/8in LH steel male is a precision spherical bearing component engineered for suspension tuning, chassis fabrication, and high-performance drivetrain modifications. Mechanics and fabricators rely on these rod ends to replace worn linkage joints, build custom control arms, and dial in suspension geometry on everything from drag cars to street machines. The left-hand male thread configuration provides directional adjustability essential for fine-tuning ride height, camber, and bump steer in performance applications.

This CM series rod end features a spherical bearing design with a 5/8-inch bore and 5/8-18 left-hand male thread, allowing smooth articulation through suspension travel while maintaining precision alignment. The steel construction with zinc oxide finish resists corrosion in underbody environments and delivers durability through thousands of suspension cycles. The spherical bearing geometry accommodates angular misalignment while the threaded body accepts jam nuts and adjustment collars, making it ideal for adjustable suspension arms and steering linkage where field tuning is required after initial installation.

Fabricators and suspension shops most often specify these rod ends for custom A-arm construction, tie-rod extensions, and sway bar links where adjustability and precision bearing action outweigh OEM solid joints. The left-hand thread suits applications where the corresponding right-hand threaded adjuster creates a locking pair—a standard approach in competition and street rod suspension builds. Verify bore diameter and thread pitch compatibility with your adjustment tube or ball stud before ordering; this 5/8x5/8 sizing is common in mid-sized suspension systems on LS swaps, vintage muscle car restorations, and small-block V8 platforms.
