Construction & Design

This differential cover is crafted from heavy duty ¼” thick cast iron, chosen for its exceptional toughness and ability to absorb impacts from rocks and trail obstacles. Compared to standard stamped steel covers, this thickness significantly improves protection for your front differential. The cast iron is finished with a durable black powder coat that guards against corrosion and wear, ensuring long-lasting performance even in harsh off-road environments.

The smooth, contoured exterior reduces the chance of rocks catching on the cover, which can cause damage or slow your vehicle on difficult terrain. The high fill plug is strategically placed and reinforced to prevent damage from trail debris, maintaining a leak-free seal and simplifying fluid changes. Additionally, the included calibration plug is factory-set to the correct oil level, preventing overfilling and ensuring optimal lubrication for your differential.
