Overview
LINKAGE ADJUSTER Product Overview
LBA8-36 / LBAX8-36 / ALBA8-36 is a female-male linkage adjuster with 1/2-20 LH male thread and 1/2-20 RH female thread. Overall length (A) = 3.625″, body length (B) = 1.81″, male thread length (C) = 1.35″, female thread bore reach (D) = 1.25″, hex diameter (E) = 0.75″.
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: LBA8-36. Chromoly: LBAX8-36. Aluminum: ALBA8-36. Special lengths available in volume. Metric size LBA-M10 available for metric rod ends.

FAQ
LINKAGE ADJUSTER Frequently Asked Questions
What is the LBA8-36 linkage adjuster used for?
The LBA8-36 (and its LBAX8-36 chromoly / ALBA8-36 aluminum siblings) is a female-male linkage adjuster with a 1/2-20 LH male thread and 1/2-20 RH female thread — thread one rod end into each side, then rotate the body to extend or shorten the assembly, a low-profile alternative to jack screws for steering links, tie rods, and pull-pull control systems.
What are the overall dimensions of the LBA8-36?
Overall length (A) is 3.625 in., body length (B) is 1.810 in., male thread length (C) is 1.350 in., female thread bore reach (D) is 1.250 in., and hex diameter (E) is 0.750 in..
What material options are available for this 1/2-20 linkage adjuster?
Three material variants share this size: LBA8-36 in carbon steel (silver zinc plated), LBAX8-36 in 4130 chromoly (heat treated, silver zinc plated), and ALBA8-36 in aluminum (black anodized).
How does the LH/RH thread combination on the LBA8-36 work?
The male end uses a 1/2-20 left-hand thread and the female end a 1/2-20 right-hand thread, so rotating the hex body extends or shortens the linkage without needing to remove the rod ends threaded into either side.
Are custom lengths or metric sizes available for this adjuster?
Yes. Special lengths are available in volume, and SYZ also offers a metric LBA-M10 size for metric rod ends alongside this 1/2-20 inch/metric size.
What should I confirm with SYZ before ordering the LBA8-36?
Confirm which material variant you need (LBA8-36 carbon steel, LBAX8-36 chromoly, or ALBA8-36 aluminum) and your required overall length, since special sizes are available in volume on request.
