Peek under the hood of a customized diesel truck and chances are high you'll see the pipes with a WCFab logo on them. Wehrli Custom Fabrication offers performance upgrades and fabricated parts for all of the domestic diesel truck platforms – Cummins, Duramax, and Power Stroke. This company has a solid reputation among diesel modding enthusiasts for a reason. All of the products are made in the U.S.A. from start to finish, and their high build quality and superior craftsmanship are evident right out of the box. They fit like a glove, perform as advertised, while their excellent finishes and eye-catching colors dress up the engine bay.
The WCFab product line includes high-flow intakes, downpipes, intercooler pipes, single- and twin-turbo kits, coolant tank kits, and more. The Single Turbo Install Kit is an essential upgrade for the Duramax that allows for the installation of an S400 or S300 turbocharger. It includes an air filter, a 4-inch intake pipe, 3-inch intercooler pipes, and a 3-inch aluminum Y-bridge, while coming with all of the needed components. The downpipe connects to the V-band flange, eliminating the need for cutting. If you're looking to swap the failure-prone stock CP4 pump on your Duramax, Wehrli Custom Fabrication has street and racing CP3 conversion kits.
WCFab was started in 2010 by the Wehrli brothers. The work at their father's cabinet shop since a young age has imparted skill and attention to detail to them. Now that Jason, Ryan, Mitch, and Chad Wehrli have their own successful company, they are actively involved not only in management and quality control but manufacturing processes as well. They do CNC operations, metal fabrication, powder coating, etc. shoulder to shoulder with their employees. The production takes place in a well-equipped 35,000 sq. ft. facility in DeKalb, Illinois. In-house manufacturing allows the experts at WCFab to have full control over the quality and craftsmanship, while maintaining the production pace to keep up with the high demand.
