Description

The Wehrli 100478-GRY is a 2001-2004 LB7 Duramax S300 Single Turbo Install Kit, designed to upgrade the turbocharger system on Chevrolet Silverado 2500 HD and 3500 HD trucks. It includes a 4" fabricated aluminum intake, 3" hot and cold side charge pipes, a billet Y-bridge, stainless steel oil lines, a T4 fabricated steel pedestal, and a high-temp ceramic coated downpipe. The kit requires a WCFab Billet forward-facing thermostat housing kit and may require machining the turbo's exhaust housing if not purchasing a genuine Borg Warner turbo from WCFab.
