Rod End - 5/16in x 5/16in RH Aluminum Male

The QA1 Rod End – 5/16in x 5/16in RH Aluminum Male is a precision spherical rod end connector engineered for steering linkage, suspension geometry, and control arm applications where smooth articulation and reliable load transfer are essential. Built from red anodized aluminum, this right-hand male threaded component delivers the bearing characteristics and corrosion resistance demanded in marine and motorsport environments where salt exposure and vibration are constant challenges.

The 5/16-inch bore paired with 5/16-24 right-hand thread creates a direct, compact interface suitable for both OEM and custom applications. Spherical bearing geometry allows for angular misalignment without binding, reducing stress concentrations in the attached linkage and extending component life under dynamic load cycles. The aluminum construction keeps overall weight minimal while the red anodized finish provides corrosion protection in saltwater and high-humidity environments. Each unit is manufactured to QA1's standard for concentricity and bore tolerance, ensuring precise fit without play.

This rod end is commonly specified in marine drive systems, racing suspension setups, and offshore power equipment where steering response and structural integrity matter. Weekend boaters upgrading stock linkage and serious competitors building custom suspensions both rely on QA1 rod ends for predictable articulation and durability. The compact 3 x 0.65 x 3.6 inch footprint fits tight spaces without sacrificing load capacity, making it a practical choice for retrofit and new-build projects alike.

QA1 rod ends are stocked across the marine, automotive, and motorsport sectors and are recognized for consistent dimensional accuracy and reliable performance in high-cycle applications. When steering feel, suspension geometry, and corrosion resistance combine in your design requirements, this aluminum spherical rod end delivers a proven solution.
