Powerstroke Differential Cover

Yes—finned aluminum covers add surface area for heat dissipation, lowering gear oil temperature under sustained heavy loads. However, the primary value of an aftermarket cover is structural strength: stamped factory covers flex under load, while SPELAB's thick aluminum casting resists deformation from impacts and high torque. For trucks doing heavy towing or rock crawling, both the cooling benefit and impact protection matter.

The 1999–2016 Ford Super Duty F250/F350 uses a Sterling 10.5" axle often called a "Dana 60" in 2005+. The Dana M275 (2017+) is a larger 10.8" axle found on F250/F350 with the higher GVWR package—both use 14-bolt patterns but are not interchangeable. The Dana 50/60/70 10-bolt covers fit older Chevrolet/Ford swaps. Always check your axle stamp on the housing before ordering.

Yes—but only if the existing gear oil is clean and at the proper level. Most installers do a drain-and-fill at the same time since you have the cover off anyway. Use the cover's drain plug if equipped, or remove the fill plug to check level. Always use the manufacturer-specified gear oil weight (typically 75W-140 synthetic for heavy-duty applications) and Torque the cover bolts to spec to avoid leaks.

The 2008–2010 6.4L Powerstroke uses the Dana Super 60 front axle and a Sterling 10.5" rear axle. SPELAB's Dana Super 60 cover ($155, 42% off) and Sterling 10.5" cover ($155, 42% off) are both available. The Dana Super 60 is a 10-bolt pattern; the Sterling uses 12 bolts. Verify your axle stamp on the housing cover before ordering—6.4L rear covers are different from 6.7L covers.

No periodic maintenance is required on a solid aluminum differential cover. Check the gasket/seal at each oil change for leaks. Some SPELAB covers include a magnetic drain plug to collect gear wear particles—check it at every service. Unlike fluid-based coolers with lines and fans, a finned cover is purely passive. Inspect mounting bolts for tightness after the first 500 miles after install.
