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.
This looks so much beater than the rusty oem. Also like being able to see the diff oil level thru the sight glass. Also makes for easy fill and drain for regular maintenance.
Install was easy it just took a minute to get around to do it due to life.. Great product! Will purchase more parts in the future through Spelab!

Perfect fit
I was really impressed with the quality of the welds, bends, and overall fitment. I added a 51" straight through muffler to the 5" kit and it sounds great. Nice tone at idle and when you get on it but it is quiet on the highway and when cruising
it looks great but fitment was a huge pain for the shop to fit and requires quite a bit of cutting but other than that im happy with it

High quality pipe
The down pipe is very well made and is a better fit in the tight space it has all the sensor holes and it’s already wrapped it heat tape it seems to be very well made I am very pleased with this down pipe.
Looks great. Fit on my 2023 Ford F150 Powerboost. I cut the spare tire crossmember off to get to it better. Happy to be able to change fluid easily. Dont know of long term performance yet. I've only had it installed for 3 weeks.

Fit great! Only company I could find that sold a stainless system
The installation was very self explanatory. I had more trouble removing the factory system as I didn’t have a sawsall on hand. I never quite figured out where exactly the U-bolt clamp went but I put it in the spot where it could reach the a hanger on the frame. Publishing instructions on a PDF file on the website would have been helpful for that to say the least. It definitely opened up some power on the truck and gave it A LOT more noise. I ended up ordering a muffler from SPELAB as well under the assumption that the muffler was made for the system and would go right in to which I was correct and it fit perfectly and cut down on the drone. The quality of the kit was great as well, the thickness of the tubing was great and rivaled other brands that used to make turbo back kits in the past. The clamps were an even nicer touch as they don’t crush the rope and makes it so much easier to service if the need were ever to arise, which with how great the quality of this kit was, I don’t see that happening. 10/10 would recommend this kit to anyone with the 04.5-07 platform, and have already. I’ll include some pictures of what it looked like once installed as well. Thanks guys!
I have a 2017 Ram 2500 2wd and looking to make it last as long as possible. With extra fluid capacity and cooling fins, I felt that this is better than stock. The hardware that came with it looks great and appreciated because I was going to replace the old anyways. Even the gasket is heavy-duty and looks like it's reusable if needed. Not a thin felt like material but a thicker quality rubber. Shipping was like 4 days. I am pleased with my purchase and would highly recommend it.

Worth every penny
Highly recommend clean, good quality, fast shipping. 100% haves my business is had my power coated
Everything went in and on very smoothly everything fit and as should only thing I will say is does not come with bolts for up pipe and the gaskets are decent but would upgrade to some mahle gaskets and get a set of ppe up pipe bolts other than that very solid affordable set of parts the coating on the up pipe will burn off due to heat but it does not affect performance of part or affect truck at all definitely recommend if your looking for performance parts while trying to save some money it definitely gave my Lly duramax the tone and power I was looking for!
