Laser String II is the first 3D laser measurement device of its kind for performing four wheel alignments, chassis inspection, and chassis construction using the vehicle centre line as reference. Laser String II simulates traditional three string alignment method used by racers but adds a third dimension in the vertical axis. It also has a much greater potential for other uses beyond suspension alignment.

The Laser String is currently used by over 75% of the NASCAR teams and considered the corporate standard for many of the top championship teams. Not only is the Laser String II the standard gauge for chassis setup, it is also considered one of the key components in stock car frame construction and body panel placement.

Laser String II is a custom built three head laser system for projecting three vertical parallel reference lines. The centre laser beam is used to establish or target the vehicle centre line. The two outer laser beams, on each side of the race car, are calibrated to the centre laser beam.

Using the triple is very simple. Place the gauge on the ground, level the high precision bubble level, align the centre laser to your vehicle centre line, and your ready to go.
