Chevrolet Silverado 3500 HD Turbo Swap Kit — Wehrli S300, Bengal Grey, 01-04. A complete single fixed-vane kit to convert your 6.6L LB7 from stock IHI to an S300 setup.

Built by Wehrli Custom Fab (WCFab), it upgrades the full charge-air path: 4" aluminum intake with heavy-duty air box and dry filter with pre-filter; 3" mandrel-bent 14-gauge hot/cold piping; and a 3" billet Y-bridge replacing the restrictive upper manifold. A ceramic-coated 3" downpipe mates to the factory front pipe (V-band), so no cutting. Stainless braided Parker oil lines are included; turbo mounts on a T4 pedestal. Note: forward-facing thermostat housing WCF100405 is required, and an HX40 outlet at the turbo is needed. Bengal Grey powder coat. If supplying your own turbo, share specs for fitment.
