ATS Differential Cover for Dodge (2001-19) 6.6L Duramax, Chevy/GMC (2001-19) 11.5 Inch 14-Bolt Rear

The ATS Differential Cover for Dodge/Ram Cummins is an ATS Diesel Performance upgrade for trucks that see added power, heat, or heavy towing. ATS designs its parts around the failures it sees in its own transmission and engine work, so each upgrade targets a known weak point.

ATS Diesel Performance has built diesel transmissions and performance parts since 1993. ATS designs, engineers, and manufactures most of its products in-house at its Arvada, Colorado facility, and tests them at altitude on the same long grades its customers tow on.
