The STR420 T is a fully versatile computerised truck and commercial vehicle computerised wheel aligner from Supertracker. Capable of aligning both Single Steer and Twin Steer commercial vehicles, this aligner allows alignment checks to be carried out virtually anywhere in the workshop. 

When used in combination with a set of standard car heads, this unit becomes a "hybrid". Able to align both trucks and cars using the same workstation, eliminating the need for two separate wheel aligners.
