Aluminum Alloy Heat Sink Oil Cooler

The Spelab differential cover serves multiple functions, including protecting the differential, sealing it, and storing differential fluid. Its innovative design incorporates an external heat sink with a significant contact area to enhance heat dissipation, complemented by internal diversion grooves that align with the fluid's flow during gear rotation for superior lubrication. Constructed from A380 aluminum alloy, this cover offers a substantial improvement in cooling performance compared to traditional iron covers. The product is available in Billet Aluminum and Cast Aluminum styles, with billet options generally considered more durable. An external observation mirror with a floating ball is included for easy oil level monitoring, even if the mirror surface becomes obscured over time. The exterior features a black wrinkle paint finish for rust resistance. This differential cover is designed for Chrysler 9.25" axles with 12 bolts, and fitment includes various Dodge Challenger, Charger, W100/W150, W200/W250, D300/D350, Ramcharger, Dakota v8, Durango, RAM 1500, and RAM 2500 models across different year ranges. However, a note advises that the year and model may not guarantee compatibility, and users should confirm their axle is a Chrysler 9.25" 12 Bolt. The design increases cover thickness by approximately 0.5 inches but does not significantly impact ground clearance.
