GM Duramax LLY-LMM 6.6 Liter SS 12pt lower rocker cover bolt kit. Application-specific bolts replace factory hardware with stronger fasteners that hold their clamping force through repeated heat cycles. The compact 12-point head makes tight spots easier to reach.

Made from polished ARP Stainless, it resists rust and corrosion while delivering strength well beyond Grade 8 hardware.
