About Stemco: Engineering Safety for the Commercial Vehicle Industry

Since 1951, Stemco has been a cornerstone of the commercial trucking industry, designing and manufacturing heavy-duty components that keep fleets on the road safely and efficiently. Founded and headquartered in Longview, Texas, Stemco has built a reputation over seven decades for producing precision-engineered parts that meet the demanding requirements of Class 6–8 trucks, trailers, and other commercial vehicles.

Stemco's philosophy is straightforward: safety and durability are not optional. Every product in the Stemco lineup is built to minimize downtime, reduce total cost of ownership, and give fleet operators the confidence that their vehicles will perform mile after mile. This commitment to focused innovation has made Stemco a trusted name among fleet managers, owner-operators, and commercial vehicle technicians nationwide.

Stemco's Core Product Lines

Stemco's catalog covers the critical areas of a commercial vehicle's axle and steering systems. Their wheel seals are among the most recognized products in the industry, engineered to prevent lubricant leakage and keep contaminants out of wheel-end assemblies — a small component with an outsized impact on safety and maintenance costs. Proper wheel-end sealing is one of the most effective ways to extend bearing life and avoid costly roadside failures.

For steering system integrity, Stemco is equally well-regarded. Their steering king pin repair kits provide everything needed to restore worn king pin assemblies to factory tolerances, helping fleets maintain precise steering response and reduce tire wear. Complementing these are Stemco's steering king pin sets, which offer a straightforward solution for full king pin replacement on a wide range of commercial axle applications.

Stemco also produces steering tie rod assemblies designed to withstand the rigors of heavy-duty use, delivering consistent steering geometry and long service life even under the stress of fully loaded commercial vehicles. Proper tie rod maintenance is critical to driver safety and even tire wear across a fleet.

Rounding out their wheel-end product line, Stemco's axle hub caps provide reliable protection for axle spindle ends, preventing contamination from road debris, moisture, and dirt. Whether for a drive axle or a trailer axle, Stemco hub caps are built to the same exacting standards as the rest of their product range.
