Wehrli Custom Fabrication WCF100235-GB 3-Inch Y-Bridge Kit Gloss Black Duramax LBZ/LMM

The Wehrli Custom Fabrication WCF100235-GB is a high-flow 3-inch Y-Bridge kit designed specifically for 2006-2010 Chevrolet/GMC Duramax LBZ and LMM diesel engines. This bridge-only kit addresses the critical weak points found in the factory design, delivering superior performance and reliability for custom builds and racing applications.

Key Features:

• Improved bolt-together two-piece design eliminates boost leak issues common with factory slip-in style bridges
• 3-inch high-flow construction maximizes airflow to the engine for increased performance
• 3-inch bead roll connection at inlet for secure, leak-free fitment
• Direct bolt-on installation to OEM intake runners
• Professional gloss black powder coat finish for a custom appearance
• CNC-machined construction using precision fabrication techniques
• Made in the USA with premium materials and craftsmanship

The factory LBZ/LMM Y-bridge suffers from a weak slip-in connection design with minimal structural support, making it prone to separation under boost pressure. This results in poor drivability, performance losses, and frustrating boost leaks. The WCF100235-GB replaces this failure-prone component with a robust bolt-together assembly that maintains proper sealing even under high boost conditions. The increased 3-inch diameter throughout the bridge reduces airflow restriction compared to the stock component, supporting higher horsepower builds and improved throttle response.

What's Included:

• Two-piece bolt-together Y-Bridge with gloss black powder coat finish
• Mounting hardware for installation

Note: This is a bridge-only kit and does not include intake pipes or other components. Perfect for enthusiasts building custom intake systems or upgrading individual components on their LBZ/LMM Duramax powered trucks.
