1.25" Standard Tube Adapter Left Hand 1.5(ID) 12(TPI)
1.25" Standard Tube Adapter — Left Hand, 1.50" ID, 12 TPI — Weld-in threaded bung for link-suspension builds. Designed so most of the heim’s shank sits inside the tube for added support by both the bung and the tube—our preferred way to build the “bottom-side” parts that see the dirt first. This model fits 1.25" LH heim joints. Sold individually.

Installation
- Difficulty: Intermediate (welding required)
- Welder Setup: Correct heat/input; start your puddle on the tube to avoid warping the threads
- Do Not: Do not weld with the rod end threaded inside—different cooling rates can lock parts together
- Cool Down: Allow to cool completely before threading rod ends into the adapter
- General: Prep/clean tube I.D.; ensure concentric fit; tack, check alignment, then stitch-weld in short passes
Ream/clean threads after welding if needed. Anti-seize is recommended on initial assembly.
Match this LH bung with a 1.25" RH mate to enable easy length adjustments without removing the link from the vehicle. Ask us about FFS Professional Installation services.
