Why Does PML Make Two Covers For the Dana 80?

PML offers two covers for the Dana 80 differential so that folks can select the cover that works best for a particular vehicle. Generally speaking, the straight fins cover was designed with 1999 and older trucks in mind and the patterned fins cover with new trucks.

Here are the differences between the two covers:

1. Design — straight fins or patterned fins
2. Clearance — the straight fins cover (part number 6065) is about 5 inches deep and the patterned fins cover (part number 9520) is about 3.8 inches deep so check for sway bars, spare tires, and such close to the stock cover
3. Fill Hole — the straight fins cover has one hole for fill and level check and the patterned fins cover has separate level check and fill holes
4. Matching Front Cover — both Dana 80 covers have matching front covers. On 1999 and newer vehicles the patterned front cover will clear the steering linkage. On older trucks, the straight fins cover will clear the ring gear. Configurations vary and lifted trucks might have different clearance.

Both covers hold about the same amount of fluid over stock. The straight fins cover is deeper than the patterned fins cover, but it has a round pumpkin shape so it only holds a few ounces more than the patterned fin cover.

For the matching front covers: See part number 10737 (has steering linkage clearance) or part number 9426 for matching patterned fins or part number 6063 for straight fins.
