Wehrli Custom Fabrication WCF100235-RAW LBZ/LMM Duramax 3" High Flow Y-Bridge Raw Aluminum

The Wehrli Custom Fabrication WCF100235-RAW is a high-performance 3-inch Y-bridge designed specifically for 2006-2010 LBZ/LMM Duramax engines. This bridge assembly replaces the factory slip-in style Y-bridge that is prone to separation under high boost conditions, providing a significant upgrade for custom turbo builds and high-performance applications.

Key Features:

• 3-inch high-flow design maximizes airflow to the engine
• Two-piece bolt-together construction reduces risk of bridge separating under extreme boost
• Bolts directly to OEM intake runners for straightforward installation
• 3-inch bead roll connection at inlet for secure fitment
• Includes O-ring seals for bridge inlet and intake runners
• Raw aluminum finish ready for polishing, painting, or custom powder coating
• Made in the USA with precision fabrication

Important Notes:

This is the bridge assembly only and does not include upper cross-over or passenger side intercooler pipe. It serves as a direct replacement for the Y-bridge used in kits WCF100163 and WCF100164. Designed for use with aftermarket high-flow piping and turbo kits running higher boost pressures. Raw finish requires protective coating or sealant to prevent oxidation and corrosion.
