Chevrolet Silverado 2500 HD Turbo Swap Kit - Wehrli - S300 - Flat Black - 01-04. Designed for 6.6L LB7 trucks, this fixed-vane swap replaces the stock IHI with an S300-based system using robust WCFab components.

This kit refreshes the entire charge-air path for strong flow and reliable fitment. It adds a fabricated intake and air box, high-flow charge pipes, a billet Y-bridge, stainless braided oil lines, and a T4 pedestal for popular S300 turbos (sold separately). A ceramic-coated 3 inch downpipe connects to your existing V-band front pipe—no exhaust cutting.

Features

• 4 inch fabricated aluminum intake, air box, and premium dry filter with pre-filter cover
• 3 inch mandrel-bent 14 ga hot- and cold-side aluminum charge pipes
• 3 inch fabricated billet high-flow Y-bridge with cold-side pipe
• Stainless braided Parker oil feed/drain; feed from main oil galley
• T4 pedestal with hardware; S300 compatibility (turbo sold separately)
• 3 inch ceramic-coated downpipe; HX40 outlet at turbo, mates to existing V-band
• Driver-side trans dipstick relocation, silicone boots, T-bolt/V-band clamps, heat wrap
• LB7 requires WCF100405 forward-facing thermostat housing for clearance
