The Eclipse upper body tram allows the tech to accurately measure points under the hood. The automatic leveling, that is an industry first, allows the measurements to be taken in any situation from the two post lift to the frame machine. Bolt and stud adapters allow the upper body tram to connect to fender bolts, radiator supports, strut towers and more. This measuring Bar uses the Laser targets that comes with the original system. NO need to buy additional targets.
