Product Description

The Wehrli Custom Fabrication WCF100325 L5P Duramax T4 Turbo Pedestal is a heavy-duty fabricated mounting solution for custom turbocharger builds on GM 6.6L L5P Duramax engines. It allows a T4-flange-style turbocharger to be mounted in an L5P application and is designed for performance-oriented and custom racing configurations.

The pedestal uses 2-inch OD, 11-gauge stainless-steel tubing and features a black high-temperature ceramic-coated finish. It is engineered to work with OEM or Wehrli Custom Fabrication 2-inch high-flow turbo up-pipes, providing compatibility with supporting components used in custom L5P turbo systems.

The WCF100325 is intended for 2017-2026 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD models equipped with the 6.6L L5P Duramax diesel engine. It is a custom turbo mounting component rather than a complete turbocharger system, so the selected turbo, oil lines, up-pipes, exhaust components, and other supporting hardware must be compatible with the complete build.
