Sway Bar Link Fab Kit - 3/4" Chromoly Heim Joints + Bungs for 1.75" OD Tubing

Build Custom Suspension Links That Actually Hold Up — The Right Way

Stop using undersized hardware on your suspension builds. This complete fabrication kit from 50 Caliber Racing gives you everything you need to build custom sway bar links, tie rods, radius arms, and control arms for 1.75" OD tubing. The 3/4"-16 x 3/4" bore chromoly heim joints are made from 4130 steel with a nylon/Teflon PTFE liner, rated to a static radial load of 28,081 lbs. Matching weld-in bungs and jam nuts are included for both left and right hand threads — ready to cut, weld, and thread. Available with or without high misalignment spacers.

Why Chromoly Beats Standard Steel for Suspension Links

4130 chromoly is not just a marketing term — it is a specific alloy of chromium and molybdenum that delivers significantly higher tensile strength than mild steel at the same weight. For suspension links that see constant dynamic loading, shock loads, and articulation stress, that strength margin is what keeps your geometry intact when things get rough. The PTFE liner in these heims eliminates the need for grease and reduces friction-induced wear, so the joint stays tight and smooth over thousands of miles of abuse. Pair that with the full-length chromoly bungs and you have a link assembly that is stronger at every connection point than anything you can buy off the shelf.

Built a full set of radius rods for my rock crawler with these. Two seasons of hard wheeling and zero slop. The load rating is no joke. — Verified Buyer

Used these for custom sway bar links on my Jeep. Perfect fitment on 1.75" DOM tubing, both wall thicknesses. Great kit for the price. — Verified Buyer
