These Trailing Arms made with 1/8” heavy-duty steel plating that makes them unstoppable. What kind of steel you ask? We’re not spilling the beans, but this ain’t your grandfather’s steel. It has a better strength-to-weight ratio than your run-of-the-mill steel, meaning it’s stronger but not heavier. We boost strength with a design that cradles the shock and sway bar link mounts in the center of the arm. Plus, we give you hex billet sway bar links that are stronger. Combine that with internal gussets, zinc-plated bushings, and hand-welded seams, and you’ve got trailing arms that know how to work.
