About Alliance Truck Parts

Alliance Parts is a well-established aftermarket brand operating under the umbrella of Daimler Trucks North America (DTNA) — the largest heavy-duty truck manufacturer in North America. Built to serve the commercial transportation industry, Alliance Parts offers a comprehensive portfolio of new and remanufactured components designed for all makes and all models of medium- and heavy-duty trucks and buses. Whether a fleet operator is running Freightliner, Kenworth, Peterbilt, Volvo, Mack, or International equipment, Alliance products are engineered for true cross-make compatibility.

A Brand Built on All-Makes Reliability

What sets Alliance apart in the crowded aftermarket space is its commitment to meeting or exceeding original equipment specifications across an exceptionally broad range of product lines. With over 50 product lines, the Alliance catalog spans critical maintenance and repair categories including brakes and wheel ends, HVAC, engine components, suspension, fluids, electrical, cooling systems, and more. Every part is rigorously tested to deliver the fit, finish, and performance that commercial fleets depend on to minimize downtime and maximize profitability.

Alliance Parts is backed by the engineering resources and quality standards of Daimler Trucks North America, which also supports renowned brands such as Freightliner, Western Star, and Thomas Built Buses. This heritage translates directly into parts that fleet managers and independent owner-operators can trust mile after mile. Retail access is broad as well — Alliance parts are available at more than 800 locations across the U.S. and Canada, including authorized dealerships and major travel center chains.

Tires and Maintenance Components for Every Haul

Among the most sought-after products in the Alliance lineup are its commercial tires, which reflect the brand's focus on durability and value for working vehicles. Alliance also covers smaller but equally important maintenance components such as windshield washer pumps — the kind of detail-oriented product coverage that makes Alliance a one-stop solution for fleet upkeep. The brand's cross-reference tool consolidates data from top OEM and independent manufacturers, making it straightforward to identify the right part for any specific truck make and model.

Quality You Can Count On

Alliance Parts products are designed to deliver reliable performance without compromising on value. The brand's all-makes philosophy means that purchasing decisions are simplified for mixed fleets, and the wide distribution network ensures that critical parts are rarely far away. For fleet managers, independent shops, and owner-operators alike, Alliance represents a trusted name in heavy-duty commercial vehicle maintenance.
