Chevrolet Silverado 3500 HD Coolant Pipe – Wehrli Upper, Deore Gold (2006–2010). This aluminum hard pipe replaces the factory rubber upper coolant hose on LBZ/LMM 6.6L Duramax trucks for sturdy, consistent performance.

Built for 2006–2010 Silverado and Sierra 2500/3500 HD with LBZ/LMM, it improves heat resistance and long-term reliability while maintaining proper coolant flow and fitment. The Deore Gold powder coat helps fight corrosion, and the kit includes silicone boots and stainless steel T-bolt clamps for secure connections. Directly replaces GM 19330105, 15792824, and 25833204. Note: this pipe does not include a WCFab badge.
