Rod End - 5/16in x 5/16 LH Female w/Stud

The Rod End – 5/16in x 5/16 LH Female with Stud from QA1 is an essential suspension and chassis component for serious vehicle builders and performance mechanics. This left-hand threaded rod end facilitates articulated joints in control arms, tie rods, sway bars, and custom fabrication work where adjustability and durability matter. Whether you're building a street rod, competition suspension, or restoring a classic with modern geometry, this precision fastener delivers the reliable pivot action modern motorsports demands.

QA1 rod ends are engineered with hardened steel construction and sealed needle bearings that resist lateral loads, vibration, and binding during suspension travel. The 5/16-inch bore diameter accommodates standard mounting hardware, while the integrated stud design eliminates the need for additional fasteners and simplifies installation into fabricated brackets or OEM attachment points. The left-hand female configuration allows reverse-threaded adjustment without removing the entire assembly—a feature that streamlines fine-tuning ride height, wheel alignment, and suspension geometry during setup and cornering diagnostics.

Mechanics and fabricators rely on QA1 rod ends for custom A-arm construction, track-focused builds, and high-angle suspension geometries where factory components fall short. Compact dimensions (3.05 x 0.85 x 3.85 inches) and lightweight design (0.11 lbs) minimize unsprung mass while maintaining the strength required for aggressive driving conditions. Installation requires no special tools beyond basic hand wrenches; simply thread onto your control arm or custom bracket, lock with the provided nut, and verify smooth articulation before final torque.
