XDP carries the XDP Engine Oil Pan Bolt Kit (Black-Phosphate) XD624 that will replace the stripped bolts on your 2001-2016 GM 6.6L Duramax LB7/LLY/LBZ/LMM/LML.

These (18) Class 10.9 bolts feature 150,000 PSI tensile strength for durability and a black phosphate coating that works as an anti-galling agent.

The flange on the bolts distributes pressure where the fastener meets the surface, removing the need for a washer.
