GM Duramax LB7-LMM 6.6 Liter 12pt oil pan bolt kit. These bolts provide even clamping along the pan rail for a proper, leak-free seal. The compact 12-point head makes tight spots easier to reach.

Made from heat-treated 8740 chrome moly with a black oxide finish, it is far stronger than factory and Grade 8 hardware.
