Dorman Transfer Case

About Dorman Products

Dorman Products has spent more than a century doing something deceptively simple: finding the parts that fail most often on cars and trucks, and engineering better replacements for them. Founded in 1918 and headquartered in Colmar, Pennsylvania, Dorman began as a small distributor supplying hard-to-find fasteners and hardware to independent garages. Over the decades, that scrappy problem-solving spirit grew into one of the aftermarket's most trusted and prolific manufacturers, with a catalog that now spans tens of thousands of SKUs across virtually every vehicle system.

What sets Dorman apart is its commitment to going beyond simple one-for-one replacement. The company's flagship OE FIX line re-engineers components to address known original-equipment failure points — rather than just reproducing the same part that broke in the first place. That philosophy shows up across product lines, from suspension hardware to drivetrain components to engine internals. It's the reason professional technicians and serious DIYers alike reach for Dorman when the OEM solution has let them down.

Dorman markets its products under several well-known sub-brands, including OE Solutions, HELP!, and Conduct-Tite, covering everything from complex electronics modules to basic clips and fasteners. The company operates through Light Duty, Heavy Duty, and Specialty Vehicle segments, meaning the catalog serves passenger cars, full-size pickups, commercial trucks, and off-road vehicles alike.

Dorman's Broad Product Coverage

With more than 54,000 products available, Dorman's reach across vehicle systems is remarkable. Among the brand's highest-demand categories, Dorman Leaf Springs stand out as a cornerstone offering for truck and SUV owners dealing with worn or sagging suspension. Dorman's leaf spring hardware and assemblies are engineered to restore factory ride height and load-carrying capacity, making them a popular choice for both daily drivers and work vehicles.

On the drivetrain side, Dorman Drive Shafts and propeller shaft components — including CV joint kits and constant velocity joints — cover a wide range of truck and SUV applications. Dorman engineers these components to tight tolerances, ensuring proper balance and reliable power transfer to all four corners.

Protecting the heart of any internal combustion engine, Dorman Engine Oil Pans are precision-engineered replacements that cover an expansive range of vehicle applications. Notably, Dorman's OE FIX oil pan designs replace problematic original plastic pan sections with high-pressure die-cast aluminum alternatives — a direct response to a known and widespread failure pattern on certain domestic vehicles.
