AFE Power Pro Series Front Differential Cover with Machined Fins 20-26 GM 3.0L Duramax LM2/LZO

The aFe POWER Pro Series Front Differential Cover is built to give your GM truck stronger protection, better cooling, and easier maintenance all in one simple upgrade. Constructed from durable cast aluminum with a black powder coat finish and machined fins, it’s designed to handle tough driving conditions while also adding a clean, aggressive look under your vehicle. It also reuses the factory gasket for a straightforward installation with all hardware included. What you’ll notice most is the improved performance and consistency under load. The built-in internal and external fins help transfer heat away from the gear oil, keeping temperatures lower for better long-term durability and smoother operation. It also increases oil capacity by approximately 1/2 quart over stock, helping maintain proper lubrication during towing, hauling, or off-road use. A magnetic drain plug captures metal debris to help protect internal components, while the sight glass and calibration plug make checking and filling fluid simple and accurate without guesswork. Overall, this differential cover is designed to improve reliability, reduce heat stress, and extend the life of your drivetrain while making maintenance easier and more precise. It’s a practical upgrade that delivers real-world benefits in durability, performance consistency, and long-term value, whether your truck is used for work, towing, or everyday driving!
