American diesel truck specialist

Wehrli Custom Fabrication is an American company specialising in parts for diesel pickups. The range is aimed especially at the big American diesel engines such as Duramax, Cummins and Powerstroke. The parts are developed for people who use their trucks hard, whether that means heavy towing, daily driving or competition. The focus is on parts that fit precisely and can handle more boost, more fuel and higher temperatures than the factory parts.

Wehrli’s key products

Intercooler pipes and intake parts are popular upgrades because they improve airflow and replace factory pipes and joints that can give way under higher boost. Wehrli also offers turbo kits and parts for fitting larger or additional turbochargers, kits for additional fuel pumps, and billet brackets, pulleys and other engine bay parts. Many parts come in different colours, so the engine bay looks good too. See each product for the engines and model years it fits.

Frequently asked questions

Why upgrade the intercooler pipes on a diesel truck?

Factory pipes and hoses can expand or come loose under higher boost. Stronger pipes with solid joints give more stable airflow and fewer problems when the engine makes more power.

Can Wehrli parts be used on a truck that is still stock?

Yes, many parts such as intercooler pipes, brackets and intake parts can be fitted to an otherwise stock truck. Larger turbo and fuel kits are usually intended for trucks with more power. See the description of each product.
