About Dayton Parts

For more than a century, Dayton Parts has been one of the most trusted names in heavy-duty truck aftermarket components. Founded and headquartered in Harrisburg, Pennsylvania, Dayton Parts has built its reputation by delivering high-quality replacement parts to spring shops, distributors, dealers, and fleet operators across North America. Their unwavering commitment to driver uptime — keeping commercial vehicles on the road and out of the shop — has made them a go-to resource in the commercial trucking industry.

What sets Dayton Parts apart is the combination of a vast product catalog, precision engineering, and a deep understanding of the demands placed on heavy-duty vehicles. Whether a truck is hauling freight cross-country or making local deliveries, the components keeping it safe and roadworthy need to perform under serious stress. Dayton Parts engineers and sources its products with that reality in mind.

Suspension & Ride Quality

Dayton Parts is especially well regarded in the suspension space. Their air suspension springs are designed to support heavy payloads while delivering a smoother, more controlled ride. Air springs play a critical role in protecting cargo, reducing driver fatigue, and minimizing wear on surrounding chassis components — and Dayton Parts produces these components to meet or exceed OEM specifications. For fleets and owner-operators alike, Dayton's suspension offerings also extend to shock absorbers, which work in tandem with air springs to control vehicle motion, improve handling stability, and extend tire life on demanding road surfaces.

Braking Systems

Safe, reliable stopping power is non-negotiable in the commercial trucking world. Dayton Parts addresses this with a comprehensive range of braking components. Their air brake chambers are engineered for consistent, dependable actuation across a wide range of operating conditions — critical for vehicles operating under federal safety regulations. Complementing this, Dayton also offers disc brake pad sets designed to deliver effective friction performance and durability for heavy-duty disc brake applications.

A Legacy of Innovation and Service

Over more than 100 years in the industry, Dayton Parts has continued to innovate — expanding its catalog, refining its engineering processes, and investing in customer support infrastructure. Technicians, fleet managers, and parts professionals trust Dayton not only because of the quality of the parts themselves, but because of the depth of application coverage and the availability of technical resources that back them up. When downtime costs money, having a reliable parts partner matters — and Dayton Parts has spent a century proving it can be that partner.
