Wehrli Custom Fabrication WCF100860-SBO Duramax Upper Coolant Pipe Kit Satin Black Orange

The Wehrli Custom Fabrication WCF100860-SBO is a direct-fit aluminum upper coolant pipe kit designed to replace the factory rubber upper coolant hose on 2001–2005 GM 6.6L LB7/LLY Duramax diesel trucks. Finished in a striking Satin Black with Orange two-stage powder coat, this kit delivers both a durable upgrade and a head-turning custom appearance under the hood.

Constructed from 14-gauge aluminum, this upper coolant pipe is significantly more robust than the OEM rubber hose it replaces, offering improved resistance to heat, pressure, and long-term wear. The kit installs using high-quality silicone boots and stainless steel T-bolt clamps for a secure, leak-free connection.

Kit Includes:

• 14-gauge aluminum upper coolant pipe
• Silicone boots
• Stainless steel T-bolt clamps
• Satin Black with Orange two-stage powder coat finish
