Keep your Duramax leak free with the Merchant Automotive Turbo Drain Gasket for 2001–2004 GM 6.6L LB7.
Designed to handle high heat and pressure, this gasket ensures proper oil drainage and a tight, reliable seal during turbo service or replacement. Choose from Upper (turbo to drain pipe) or Lower (drain pipe to engine block) gasket options, both built to OE specs for a perfect fit.
If you're doing a full rebuild, simple maintenance or installing a bigger turbo, these gaskets keep your turbo's oil drain sealed up and performing at its best.
