FAQ
Will this pan fit both 12-valve (1989–1998) and 24-valve (1998.5–2002) 5.9L Cummins?
Yes. It’s designed for 1989–2002 5.9L applications. On 1989–1993 setups you’ll need to use a 1994–2002 pickup tube for proper pickup alignment.
Do I have to change the oil pan bolts?
This Big Iron pan uses 6.7L-length bolts (longer than stock 5.9L). We recommend replacing the hardware with our bolt set for correct thread engagement and sealing.
Does it include a gasket?
No. Pair it with the MAHLE OS32139 gasket (1989–2002).
What if my engine has a main stud girdle?
Use the stamped Big Iron version designed to clear girdles (search our site for “BI591224VOPMS”).
Is capacity different from OE?
It is built as an OE-style replacement with improved draining and a reinforced lip; capacity remains comparable to stock.
