This LH 3/4"-16 Tube Insert is precision-machined to fit 1.25" inner diameter steel tubing and is tapped with 3/4"-16 left-hand threads to pair with LH Heim joints. Commonly used in 4-link suspension setups, control arms, drag links, and steering systems, it’s an essential part for off-road and high-strength fabrication projects.
Constructed from weldable steel, this insert is built for extreme conditions like rock crawling, Ultra4 racing, and mud trucks, offering maximum durability and thread engagement. Left-hand thread allows for easy link adjustment when paired with a right-hand insert on the opposite end.
