Blue Ox Tiger Trak Track Bar SystemAnyone who’s ever towed a trailer has probably experienced a bit of “tail wag” – a problem that occurs because the leaf springs in the tow vehicle start flexing from side to side. TigerTrak, by Blue Ox, is a front- and rear-stabilizing track bar system designed to combat this potentially dangerous situation. TigerTrak helps to keep the springs from flexing laterally while still allowing vertical flexing for a smooth ride. High-strength alloy steel construction makes TigerTrak units strong, durable and still easy to install. Blue Ox offers a TigerTrak model to fit all Ford F-53, E-350 and E-450 chassis, all Chevy P30, P32 and Kodiak truck 4500 and 5500 chassis, and the complete line of Workhorse front-engine gas chassis.
