The Chevrolet Duramax Twin Turbo Kit by Wehrli, compatible with the S400/Stock configuration and featuring a stunning Bronze Chrome finish, is designed for the 2001-2004 GMC Sierra and Chevrolet Silverado LB7 Duramax models. This kit is specifically engineered to enhance horsepower, improve fuel efficiency, and maintain optimal exhaust gas temperatures, making it an ideal upgrade for daily drivers and tow rigs.

The Duramax Twin Turbo Kit unlocks substantial performance potential, delivering up to 1000 RWHP based on your chosen turbo and fuel system enhancements. Key benefits include increased power for towing and hauling, combined with superior acceleration and throttle response courtesy of stock-like turbo spool characteristics.
