Hotchkis Sport Suspension upper trailing arms work to positively locate and control the rear axle. By doing this, they dramatically improve cornering and stability through increased roll stiffness and anti-sway bar effectiveness. They're fabricated from high-quality, heliarc welded, .120 in. wall steel tubing and feature CNC-machined spring perches and fluted polyurethane bushings. They come available in both standard and adjustable versions.
