aFe Pro Dodge/Ram 1500 Corporate 9.25 Rear Cover

Axle-specific differential protection

The aFe 46-70272 cover fits the specified Corporate 9.25 - 12 bolt differential. A356 cast aluminum with reinforcing ribs, black powder-coating and machined fins.

Key Features

• A356 cast aluminum with reinforcing ribs, black powder-coating and machined fins.
• M12 x 1.25 drain plug with aluminum washer, 1/8-inch npt calibration plug, 3/4-inch npt magnetic fill plug with a 6-inch reach and installed 1-inch sight glass.
• Calibration opening supports checking the correct oil level.
• Manufacturer states this cover does not require a CARB EO number.

Fitment

46-70272: The current exact listing identifies Dodge/Ram 1500 1994-2018 and Ram EcoDiesel 2014-2022 with a Corporate 9.25 twelve-bolt rear housing; an older paragraph stops in 2015. The linked manual names older 1500 gas ranges and a broad 2011-2018 3.0L line that must not be interpreted as EcoDiesel availability before the current listing's 2014 start. Later 1500/Classic named rows have exact-part retailer support and remain qualified by actual housing, engine, clearance and boxed revision, not blanket certification for all engines. Contrary retailer tables also list 2500/3500 and SRT-10; those mappings are withheld as source conflicts. The primary 2016 Ram heavy-duty guide identifies 11.5/11.8 rear axles, manufacturer heavy-duty cover manuals identify different rear families, and Dodge's SRT-10 engineering document identifies a Dana 60 rear. This is not a physical interchange test; no heavy-duty or SRT-10 application is approved by a shared 9.25 dimension or a front-axle description.

Specifications

What's Included

• One black cover 05-60445B, twelve stainless 5/16-18 x 1-inch socket-head screws, twelve flat washers, black RTV, M12 drain plug/aluminum washer, 1/8-inch calibration plug, 3/4-inch 6-inch magnetic fill plug and installed sight glass. The primary describes the drain as magnetic; the bill of materials labels it an M12 plug.
• Gear oil, axle additive, filters, couplers and tools are not established as included. Lay a continuous bead of the supplied RTV around the clean sealing face as directed. A new flat gasket is not listed, and this exact manual does not give a numerical RTV cure interval.

M12 x 1.25 drain plug with aluminum washer, 1/8-inch npt calibration plug, 3/4-inch npt magnetic fill plug with a 6-inch reach and installed 1-inch sight glass. The black cover's sight glass is installed as listed in the bill of materials. The plain 1-inch side plug and plain 3/4-inch fill plug belong to the separate raw version.

One black cover 05-60445B, twelve stainless 5/16-18 x 1-inch socket-head screws, twelve flat washers, black RTV, M12 drain plug/aluminum washer, 1/8-inch calibration plug, 3/4-inch 6-inch magnetic fill plug and installed sight glass. The primary describes the drain as magnetic; the bill of materials labels it an M12 plug.

Gear oil, axle additive, filters, couplers and tools are not established as included. Lay a continuous bead of the supplied RTV around the clean sealing face as directed. A new flat gasket is not listed, and this exact manual does not give a numerical RTV cure interval.

Fill until oil flows from the driver-side 1/8-inch calibration opening, then close the port. The exact manual gives no total quart quantity. Some retailer descriptions claim four or five quarts; no universal volume is certified from those conflicting statements. Establish the correct level separately for a rotated axle and use actual lubricant/additive requirements.

Tighten mounting screws to 12-16 ft-lb in a cross pattern. The exact manual does not give numerical M12 drain, rear Panhard or rear sway-bar torque, or an NPT turn count. Drive at least 25 miles and recheck oil level; do not borrow another cover's 63 or 324 ft-lb suspension value.

Block the tires on a flat dry surface and position a drain pan. Retain upper cover hardware while draining, then remove the cover. Clean and inspect the flat sealing face without gouging or rounding it. Lay a continuous bead of the supplied RTV around the clean sealing face as directed. A new flat gasket is not listed, and this exact manual does not give a numerical RTV cure interval. Where the illustrated rear suspension is fitted, remove the rear sway bar and Panhard bar for cover access and restore both with their original hardware at the end. Earlier suspension layouts require their actual service procedure; this is not an instruction to remove a bar the truck does not have. Install the appropriate hardware, fill by the specified level opening and inspect clearance and leaks. Follow the exact supplied revision.
