Wehrli 01-04 Chevrolet 6.6L LB7 Duramax 3in Y-Bridge Kit - WCFab Grey
Maximize intake airflow and eliminate boost leaks on your 2001–2004 Chevrolet LB7 Duramax with the Wehrli Custom Fabrication 3-inch Y-Bridge Kit in WCFab Grey. The factory plastic Y-bridge is a well-known weak point on the LB7 Duramax, prone to cracking under boost pressure and heat cycling — causing significant power loss and potential engine damage. The WCFab Y-bridge replaces it with a robust aluminum unit that flows more air and holds up to aggressive tunes and high boost levels.
The 3-inch diameter channels increased airflow to both cylinder heads, supporting higher power output. Finished in WCFab Grey powder coat for a distinctive, custom appearance. This is one of the most impactful and cost-effective bolt-on upgrades available for the LB7 Duramax diesel platform.
Fits: 2001–2004 Chevrolet 6.6L LB7 Duramax
