Steering Geometry Solutions

Historically, front axles were improperly designed for trucks that are intended to turn frequently.  To get maximum tire wear on front axle tires, the steering geometry must be corrected.  This ensures that the tires track properly in relationship to the wheelbase of the vehicle. 

The above illustration shows the improper and proper steering geometry commonly referrd to as the Ackermann Principle.  Because the steering arms are improperly designed on most trucks and buses, the geometric relationship between the steering wheels is wrong.  This makes it impossible for the wheels to properly track when turning, creating a "toe-out" wear pattern on the tires.  This can be corrected by changing the geometry of the steering axle.  It cannot be corrected by alighnment.  The alpha Steering Ackermann Correction Kit is designed to correct this problem for your vehicle.
