LINKAGE ADJUSTER Product Overview
LBA6-34 / LBAX6-34 / ALBA6-34 is a female-male linkage adjuster with 3/8-24 LH male thread and 3/8-24 RH female thread. Overall length (A) = 3.435″, body length (B) = 1.62″, male thread length (C) = 1.16″, female thread bore reach (D) = 1.06″, hex diameter (E) = 0.563″.
The LBA (carbon steel, zinc plated), LBAX (4130 chromoly, heat treated, zinc plated), and ALBA (aluminum, black anodized) linkage adjusters thread one rod end into the female socket and one into the male shank. Turning the body extends or shortens the assembly — a low-profile alternative to jack screws for steering links, tie rods, and pull-pull control systems. LH/RH thread combination allows adjustment without removing end fittings.
Carbon steel: LBA6-34. Chromoly: LBAX6-34. Aluminum: ALBA6-34. Special lengths available in volume. Metric size LBA-M10 available for metric rod ends.

LINKAGE ADJUSTER Frequently Asked Questions
What is a linkage adjuster used for?
A linkage adjuster is used to fine-tune center-to-center length in threaded linkage assemblies without removing the full assembly.
What materials are available in this series?
This series includes carbon steel zinc plated, chromoly heat treated, and aluminum black anodized options.
How do I choose the correct thread sizes?
Start with the left-hand and right-hand thread sizes, then confirm A, B, C, D, and E dimensions for fitment and adjustment range.
Why are both male and female thread dimensions important?
Because the adjuster uses a female-male architecture, both thread interfaces affect compatibility, adjustment range, and final assembly strength.
Which dimensions matter most for fitment?
Thread sizes, A overall reference, B/C/D body dimensions, and E wrench flat are the main fitment checkpoints.
Can SYZ make special sizes?
Yes. Special sizes are available in production volume for OEM or repeat fabrication programs.
