The Mag-Hytec AA 14-11.5 Differential Cover adds styling, function, and protection to the rear end of your GM 2500HD/3500HD or Dodge Ram 2500/3500. This heavy-duty differential cover makes it easy to do fluid changes with its built-in magnetic drain plug, oil dipstick to check fluid levels, and an o-ring gasket to provide a leak free seal. Built from aircraft grade aluminum, this differential cover features 303 stainless steel hardware and comes ready for installation on your truck. Requires allen key wrenches for installation and service.

Note: This is the correct cover for your 14 bolt – 11.5″ differential, even though there are only 12 bolt holes. The top and bottom bolts have been removed for the drain plug and temperature sending unit hole.

Ram Application Notes*:
Fits Ram models with leaf spring suspension only. Will not fit late model trucks with factory coil springs or airbag suspension. If you have the coil spring rear suspension, please see the AA 14-11.5 CS Differential Cover below.
