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.

Good Quality and Great Value
I was already planning to replace the radiator and coolant tube, so getting the reservoir included made this a great value. Parts arrived well packaged and everything looked good out of the box.

Looks and Feels More Durable
The aluminum upper coolant tube is a huge improvement over the factory plastic piece. The whole kit looks great under the hood and everything went together without any major issues.

Sounds great, had all the hardware good quality metal and was easy to install only con was had to take off the spare tire to install.
Main challenges are removing and sealing the factory crankcase-breather hoses, then transferring the factory O-ring without stretching or mis-seating it. Cap every disconnected factory port/tube correctly, lift the old cover straight up, keep debris out, and route the new breather hose safely—zip-tied away from moving/hot parts. Start all six bolts by hand, tighten from the center outward, and use only 4–8 ft-lb. Be gentle to avoid scratching anodized covers.
Good quality and half the big brands price love itttttt

Worth it!!!
I used a different oil catch can because it was “cheaper”. It just made a mess of my engine compartment. It couldn’t handle the pressure of the Cummins. Should have gotten this one in the first place. You get what you pay for! I have alot of SPELAB parts in my truck should have known better. Love the setup, easy to do yourself and now I don’t have to worry about it ever again. Set it and forget it! Love SPELAB!! Set up looks amazing!!!

2011+ Upper Radiator Pipe
The kit came quickly and wasn’t missing everything. The finish of the billet parts it nice and so is the powder on the pipe. Drove 2000 plus miles with with on and have had zero issues.
Loved the kit good fit and finish and easy to install. The little extraction tool helped immensely for that pesky bolt on the back. I purchased this kit because of the good reviews and I seen one on a 2018 Chevy Duramax that had been fully deleted and was asking the owner questions about the kit and where he bought it, he said SPELAB it was well worth the money and made it easier to put oil in the truck and yes does make it a lot easier to fill the engine with oil and if the old plastic ccv system cracks do to heat and and age it pushes oil on the engine and could cause a fire so it was well worth the money and piece of mind. So if you are looking for a CCV reroute kit I highly recommend this kit.

Install studs hand-tight
do not treat head studs like ordinary bolts. Clean and chase every block thread, verify hole depth and any fluid passages, then apply the supplied assembly lubricant only where specified—especially on nut and washer contact surfaces.

Good studs
Took the gamble on these. Ive installed arp studs for customers and I did these in my truck. Few thousand miles now and no issues. I can’t say they are better than arp but I can say they are just as good for just half of the price.

Intake horn with grid heater relocation
First off I purchased this intake horn/w grid heater relocation because of the price and the heating element came as a kit. I am not a truck mechanic and this part wasn't very easy for me to swap out. The parts were shipped extremely fast and well packaged this intake horn was installed in conjunction with Spelab's rid heater delete kit. I was also nervous to do this swap myself because I haven't messed with any of these parts previously. But Praise God I was able to take everything apart and install the new parts without any issues. The videos were alright also looked up a few videos on YouTube to get a better idea of what I was up against before I started. Overall Spelab has been a great experience, all the parts were very nice looking and well made. I will definitely do business with Spelab in the future. I am considering doing the head stud kit.
