2013-2024 RAM 2500 2013-2024 Ram 3500 2013-2024 Power Wagon
Note: The year and model may not necessarily be compatible. Please confirm if the axle is AAM 9.25'' with 12 bolts. For 2003-2013 models, it is a 14-bolt axle. For 2013.5+ models, it is a 12-bolt axle (this product).
Key Benefits
Enhanced Cooling Performance: Superior heat dissipation through extensive cooling fins.
Durable Construction: Made from high-quality A380 aluminum.
Easy Maintenance: Features such as magnetic drain plug and sight glass for effortless oil changes and monitoring.
Extended Differential Lifespan: Efficient lubrication pathways reduce wear and tear.
Protects the differential, seals the differential, stores differential fluid.
Innovative points:
1. The external heat sink design increases the contact area between the differential cover and the surrounding air, enhancing heat dissipation performance.
2. The internal diversion groove design aligns with the direction of liquid flow in the differential gear's rotation, ensuring maximum flow rate for better lubrication.
3. The use of aluminum alloy material significantly improves cooling performance compared to the commonly used iron material. When comparing billet to cast products, billet items are often considered more durable and built for long-lasting performance.
4. An external observation mirror with a floating ball is used to monitor the oil level. Traditional observation mirrors in the market may darken over time, reducing visibility. Therefore, the floating ball allows us to monitor the oil level even if the mirror darkens.
5. The outside with black wrinkle paint providing rust resistance.

FAQs
Q1: What is a differential cover?
A1: A differential cover is a protective casing for the differential assembly of a vehicle, designed to shield it from external damage and help manage heat dissipation.
Q2: Why should I upgrade to an aftermarket differential cover?
A2: Upgrading to an aftermarket differential cover enhances cooling, reduces wear and tear, and often provides better durability and performance compared to stock covers.
Q3: How does a differential cover improve cooling?
A3: Differential covers with cooling fins and increased surface area improve heat dissipation, keeping the differential fluid cooler, which extends the lifespan of the differential components.
Q4: Are AAM 9.25 diff covers easy to install?
A4: Yes, most aftermarket differential covers are designed for easy installation, typically requiring basic tools and minimal mechanical knowledge.
Q5: What materials are commonly used for 12 bolt diff covers?
A5: Differential covers are commonly made from aluminum or steel, with aluminum being popular for its superior heat dissipation and lightweight properties.
Q6: How do I know if a differential cover is compatible with my vehicle?
A6: Check the product specifications for compatibility with your vehicle's make, model, and differential type. Many manufacturers provide detailed fitment guides.
Q7: Can a differential cover improve my vehicle’s performance?
A7: Yes, by maintaining optimal differential temperatures and reducing fluid breakdown, a good differential cover can improve overall vehicle performance and efficiency.
Q8: What is the purpose of a magnetic drain plug in a differential cover?
A8: A magnetic drain plug helps capture and remove metal debris from the differential fluid, reducing wear on internal components.
Q9: How often should I check or change the differential fluid?
A9: It’s recommended to check the differential fluid level and condition during regular maintenance intervals, and change it as per your vehicle’s service manual or if the fluid appears contaminated.
Q10: Do differential covers require special maintenance?
A10: Differential covers generally require minimal maintenance, but it's important to periodically check for leaks, ensure bolts are tight, and inspect the condition of the fluid and magnetic drain plug.
Cover went right on and looks great. Do wish red was an option to Mach the rear one. Sight glass also just touches the tie rod end tube at full turn.

Great product
Instructions were great, could
Be more detailed but overall great product, install wasn’t bad at all, unfortunately snapped oil dipstick tube following instructions but other than that I would say the plugs in the intake could’ve been put in prior rather than leaving room for install error

Installed my new rear Diff cover on 2017 ram 3500 diesel!!!
this 2017 3500 Ram with now 111274 miles was used by PO to pull 5th wheel and now it pulls a 30 ft airstream TT.. I change out fluid at 96K with OEM cover and started looking for replacement.. this is great with magnetic drain plugs which is a great help as we change out oil every 35K miles as we tow a lot..
This new alum cover with fins is much like the AAM unit used on teh HO engines from factory with not quite the amount of and placement of fins but in the end this accomplished the goal of keeping the fluid cooler especially when towing.
One thing i did notice was the no actual instruction on what was proper level of oil in sight glass.. Usually on OEM cover you fill till the oil dribbles out the fill plug on cover and that if good..
on this model I noticed the sight glass was lower than the OEM plug determining the level need to be not the middle of the sight glass but at the TOP of the sight glass.. just saying.. the inside has fluid diversion fins so help move the oil to ponion gear and the side bearing on housing..
The fit and finish are great and it looks super cool now in the alum color.. I though about spray painting and sanding the edge of the fins to have that nice contrast but left it silver.
highly recommend and the price is right..

Fantastic Electric Cutous
I purchased a pair of Spelab Electric Cutouts for my BMW. Everything in the kit was shipped quickly, was perfectly packaged and the quality of their product is top notch. I installed the cutouts and I couldn't happier with the way they work. I was even able to pair the remote to the Homelink buttons to open and close the valves.

Egr delete kit
Very good quality kit and was easy to install!! I highly recommend it!!
Excellent quality product that definitely delivers a difference in throttle response. You can tell that the engine is breathing much better. I highly recommend this to everyone out there. Shipping was fast too!! And to top it off, the dreaded engine killing grid heater plate is gone for good! Look how bad the grid heater was after only 46,000 mi. You can barely see thru the grids. Ridiculous design by Cummins/Ram. They should be ashamed for putting that piece of junk on such a good engine. Next up, turbo tubes!
