FAQ
Do I need these bolts for a stock oil pan?No. These are for Big Iron pans with a reinforced lip. Stock pans can use standard-length hardware such as the CPP 3920400 set linked above.
How many bolts are included?The kit includes 36 extended bolts for a complete install.
Will this fit both 12-valve and 24-valve 5.9L Cummins?Yes — the hardware length is dictated by the pan’s reinforced rail, not the cylinder head/valvetrain generation.
What torque should I use?Follow Cummins factory oil pan bolt torque specs and pattern for your model year; re-torque after initial heat cycles if recommended by your service manual.
