DORMAN STEERING & SUSPENSION

Your single source for all steering and suspension components

Dorman offers the most comprehensive catalog of steering and suspension and patented chassis repair innovations in the aftermarket.

Our three product lines cover the entire spectrum of chassis needs for every type of vehicle, driver and fleet.

Premium construction and comprehensive coverage

The flagship of our three-tier steering and suspension product lines might just be the only line you ever need. The components in the Dorman chassis line are designed, engineered and manufactured to match or exceed the specifications and performance of the original equipment. They never stray from OE joint style construction as competitive products do.

The Dorman line offers our broadest and deepest range of products, covering the most popular cars and trucks on the road. That means technicians can count on seamless, predictable repairs that ensure the same smooth ride and steering feel that customers expect.

These components and assemblies boast low-friction polymer bearings. This innovative construction prevents memory steer and avoids placing undue stress on electric steering racks, while providing the strength and reliability required for heavier weight steering joints, like those on hybrid vehicles.
