Constructed from premium cast aluminum, this differential cover significantly improves thermal management compared to stock units. The combination of internal and external cooling fins actively transfers heat away from differential fluid, while the increased oil capacity provides better protection during heavy use.
The integrated magnetic plugs capture metal particles before they can damage gears, and the factory-set calibration plug ensures proper oil levels. A clear sight glass allows for quick visual inspections without removing the fill plug. The wrinkle-black powder coat finish provides both corrosion resistance and an aggressive appearance.
