Chevrolet Silverado 3500 Upper Coolant Pipe - Wehrli - Gun Metal - 01-05. This direct-fit aluminum upgrade replaces the factory rubber upper radiator hose on 2001–2005 6.6L Duramax LB7/LLY trucks.

Built by Wehrli Custom Fabrication, this rigid aluminum pipe resists heat, pressure, and expansion better than aging rubber, helping maintain consistent coolant routing under demanding use. The gun metal powder coat adds durable protection, and the kit includes high-temp silicone boots and stainless T-bolt clamps for a secure, serviceable connection. Designed for the 2001–2005 Chevrolet Silverado 3500 Duramax, it directly replaces GM part numbers 15792832 and 15198345. Made in the USA. Note: this version does not include a WCFab badge.
