The MD Alignment QCT four-laser alignment system was designed to help diagnose vehicle misalignment and other issues within 10 minutes on three-axle trucks and tandem trailers. These tools allow for checking total toe, individual toe, and rear axle thrust alignments on medium-duty vehicles from 15" to 19.5" wheels without jacking up the vehicle or using turnplates. Corrective action for changing toe and re-checking readings can be accomplished on location unless repair or replacement are needed. Available with rolling storage cabinet and lightweight carry case.
