About Us


Sport Truck USA began in 1982 as Halls Off Road, a retail store specializing in lifted suspension. In 1984 the owners of Halls Off Road created Trailmaster Suspension and began a National program, distributing the Trailmaster Brand. In 1991 the wholesale division of Halls was sold and the name changed to Truckmaster Distributing.


It was at this time, Truckmaster began to add other lines and became a full-fledged wholesale distributor of automotive aftermarket parts. At one time we warehoused and distributed over 130 different product lines. Everything from bug shields to winches.


In the spring of 1994 Truckmaster made a strategic decision to place our focus on suspension products. No more bug shields, no more tool boxes, we opted to become SUSPENSION EXPERTS.


On January 1, 2013, Truckmaster Distributing consolidated various entities including BDS Suspension, Zone Offroad Products, 4x4 Posi-Lok, and Truckmaster Distributing into one and now operates as Sport Truck USA, Inc. We also moved our operation to a new, much larger building at 491 W Garfield Avenue in Coldwater, Michigan, at that time.


Today this is our reputation. We Know Suspension. It is not unusual for jobbers and consumers nationwide to call us and ask for help in solving suspension problems. Often the product was not even purchased from us. People know, we will answer the phone within the first 3 rings, we know what we are talking about regardless of the suspension brand, and we will treat them with respect in solving the issues.


Our divisions include BDS Suspension, Zone Offroad Products, 4x4 Posi-Lok and JKS Manufacturing. We not only sell it, we design it. We install it. We test it. We write the instructions and we deal with the issues. We Know Suspension.


We understand the market. We understand channels of distribution. Whether it is a consumer or a retail store, we understand the need for everyone to buy it right.


Sport Truck USA, Inc. is here to provide products when needed, service when needed and expertise in suspension unmatched from any other distributor in the USA.
