Description

The Flashark FLES08255 is a set of long tube exhaust headers specifically designed for 1988-1997 Chevrolet and GMC C/K series trucks, including the 1500, 2500, Tahoe, and Blazer models. These headers are engineered to be compatible with 5.0L 305 and 5.7L 350 small block Chevy V8 engines, supporting both Vortec and TBI engine configurations. This kit includes the necessary hardware for installation, such as reducers, bolts, and metal gaskets. The headers feature 3.0-inch outlets with 3-bolt collector flanges. Fitment requires careful confirmation of your vehicle's year, model, engine size, and drivetrain. Specifically, the C-series trucks are for 2WD applications, while K-series trucks are for 4WD applications. For K-series vehicles, extra clearance checks around the front driveline, frame, and collector area may be necessary. For 1996 5.7 Vortec trucks, it is recommended to confirm chassis layout, O2 sensor position, and exhaust routing. Trucks from 1998 and newer are not explicitly listed and may not fit without verification of the exact model, engine, chassis, and exhaust layout. Engine-swapped or heavily modified trucks should also be verified for compatibility before ordering. Professional installation is recommended, and some users have suggested replacing OEM bolts and gaskets with new ones for optimal results. A tune may be required for optimal performance and to prevent issues like boost wandering.
