Chevrolet Silverado 2500 HD Turbocharger Kit - Wehrli - S400 Single Turbo Install - Sparkle Granny Smith - 01-04. Built for the 6.6L LB7 Duramax, this WCFab kit converts the stock IHI setup to an S400-style system in a bold Sparkle Granny Smith finish.

Engineered for airflow and durability, it upgrades to a 5" fabricated aluminum intake with heavy-duty air box and premium dry filter with pre-filter. High-flow 3" 14-gauge aluminum hot and cold-side charge pipes and a 3" fabricated billet Y-bridge replace restrictive factory pieces. A T4 fabricated steel pedestal mounts your chosen S400 (turbo sold separately), while stainless braided Parker oil feed/drain lines and a high-temp ceramic-coated 3" downpipe that mates to the factory front-pipe V-band keep the install tidy. Note: Downpipe fits Half Marmon 4.6" S400 outlet (not HX40). Forward-facing thermostat housing WCF100405 required on LB7. SXE/Race cover setups are build-to-order; non-BorgWarner turbos may require sending your unit for mock-up.
