Description

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. 

Features:

  • 8-Quart Total Capacity
  • Finned Aircraft Aluminum Housing 
  • O-Ring Gasket, No Sealant Required
  • Pre-Drilled & Tapped 1/8" Sender Port 
  • Includes Bolt Kit, Magnetic Drain Plug, & Dipstick 
  • Routine Lube Maintenance Without Removing Cover
  • Limited Lifetime Warranty On Cover, 5-Year On O-Rings

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.

Questions and Answers

Total capacity 8 quarts, what is the actual gain over stock cover?
View Staff Answer 
Answer

Your stock 11.5 differential takes about 4.5 qt’s. This Mag-Hytec AA 14-11.5 differential cover will take approximately 6 qt’s. to fill the bottom of axle tube (lower line on dipstick) and 7.5 - 8 qt’s. to the bottom of axle (top line on dipstick) . YOUR OIL LEVEL SHOULD BE BETWEEN THESE LINES

Where can I buy a replacement dipstick for this cover?
