Abstract: A tilting platform for roll testing automotive vehicles rotates the automotive vehicle so that data can be collected to determine various roll characteristics of the vehicle. The tilting platform includes a support platform that is pivotally attached to a floor hoist. A pivot pin is positioned away from the midpoint of the support platform so that a distal end of the support platform rotates downward and a proximal end rotates upward when the floor hoist is raised.

Abstract: A counterweight is proposed for engagement to a lower end of a truck transmission shift lever in a manner to extend forwardly therefrom, relative to the vehicle. The counterweight maintains a center of gravity of the shift lever vertically aligned over a pivot point of the shift lever regardless of the rearward degree of pivoting of the lever from a neutral, vertically oriented equilibrium position thereof. Such maintained vertical alignment of the lever center of gravity relative to the pivot point significantly decreases the tendency of the lever to return to vertical orientation, such return causing a disengagement of the transmission gears, particularly in high gear and during periods when power is not being transferred through the transmission while the truck is traveling over uneven terrain.
