Keep Your Rig Riding Right
A worn or broken suspension doesn’t just make for a rough ride—it destroys tires, stresses the frame, causes handling issues, and can put you out of service during a DOT inspection. At Legacy Alignment, we handle everything underneath your truck or trailer so you get a smooth, safe, and compliant ride that lasts hundreds of thousands of miles.
