OEM y-bridge assembly for Duramax engines. All parts have no damage and are degreased before sale.
LB7 engines use two different styles of y-bridge, please see pictures if you need help identifying what style you have. Both are compatible but you will need a different style CAC boot when switching.
On LLY-LMM y-bridges, we recommend replacing the o-rings between the two separate components.
LBZ-LML y-bridges may or may not include sensors.
Please select your engine generation from the menu.
