Tube End 5/8-18 LH 1-1/4in x .120in

The Tube End 5/8-18 LH 1-1/4in x .120in from Allstar Performance is a precision rod-end fitting engineered for high-performance vehicle suspension and steering linkage systems. As a mechanic working on custom builds and race-prepped vehicles, you'll recognize this as an essential component for adjustable control arms, tie rods, and suspension geometry work. Left-hand threads on tube ends allow for fine adjustment and mechanical advantage during installation, making them indispensable for tuners who demand precise alignment and component longevity in demanding applications.

This tube end features a 5/8-18 left-hand thread pattern with a 1-1/4-inch outer diameter and 0.120-inch wall thickness, engineered for welding into chromoly or DOM tubing. The specification ensures robust strength-to-weight ratio critical for both street and competition vehicles where suspension flex or deflection can compromise handling. Allstar Performance's manufacturing tolerances guarantee concentricity and threading accuracy, which directly affects your suspension geometry and minimizes binding or excessive play that would degrade steering response and increase tire wear.

Builders and fabricators rely on these tube ends when constructing custom control arms, adjustable drag-link assemblies, and steering columns in street rods, circle-track cars, and off-road vehicles. The left-hand threading pairs naturally with right-hand counterparts to create self-locking mechanical advantage, a proven design used in competition suspension systems. Proper installation requires precision bore alignment and TIG welding into prepared tubing; the 0.44 lb weight reflects its compact profile, ideal for weight-conscious builds where suspension component mass impacts overall vehicle dynamics and ride quality.
