What Wehrli Custom Fabrication does
Wehrli Custom Fabrication, Inc. (WCFab) is a privately held, founder-owned custom metal fabrication and performance parts manufacturer founded in 2010 and headquartered in DeKalb, Illinois. The company designs, fabricates, and sells high-performance diesel aftermarket components for the three dominant North American heavy-duty diesel platforms (GM Duramax, Dodge/RAM Cummins, and Ford Power Stroke), including high-flow intake bundles, intercooler pipe kits, turbo pedestal upgrades, S400 single-turbo install kits, engine swap mount systems for classic GM chassis, straight axle conversion kits, differential covers, suspension components, and forged aluminum wheels. In addition to proprietary WCFab-branded products, the company operates an authorized reseller storefront for 30+ third-party performance brands and provides in-house powder coating services in proprietary colorways.
WCFab runs three coordinated go-to-market channels: a direct-to-consumer e-commerce storefront on wcfab.com with vehicle- and brand-based navigation and a published price range from $44 to $3,295; a tiered authorized dealer program with volume-based wholesale pricing, a dealer portal, and a public dealer locator; and an in-house Performance Shop at the DeKalb facility offering custom builds, engine swaps, straight axle conversions, and warranty-backed installation labor. Customer segments span heavy-duty work/utility diesel owners, sled pull and racing competitors, SXS/UTV enthusiasts, Jeep owners, classic truck restorers performing Duramax engine swaps, and authorized resellers. The company is closely held with no disclosed external investors, no subsidiaries, no patents or trademarks recorded, and no certifications disclosed; operating geographies are primarily North American (USA) with international shipping available on an inquiry basis and a California emissions carve-out on certain SKUs.
