Chassis realignment can be accomplished front, back and up to eight different heights with this highly versatile, positive anchoring system. Low and High Range Adjustment. Height adjustment on the low setting is from 8 inches to 12 inches, allowing the system to be hooked up without raising the vehicle. Ideal for fast pulls that do not require center line gauges or universal measuring systems. Height Adjustment on the high side is from 14 inches to 18 inches. This allows the vehicle to be raised from the floor for undercarriage inspection, hanging of centerline gauges or universal measuring systems.
