2013-2026 Ram HD Heavy Duty Cast Aluminum Front Differential Cover 2500/3500 HD Raw (238042000)

Description

Excessive heat can degrade the protective qualities of differential fluid, leading to accelerated wear of gears and bearings. In limited-slip differentials, constant high temperatures can break down clutch packs and friction modifiers, reducing efficiency and traction control.

Cast from high-grade A356.0-T6 aluminum alloy, the PPE differential cover adds .41 quart of fluid capacity and features half-inch external cooling fins. Built-in windage scrapers inside the cover reduce fluid churning, lowering heat buildup and parasitic loss. Together with the vertical external fins, they form a cross-bracing structure that improves load distribution and impact resistance.

The fill plug is positioned at the factory level. Both the fill and drain plugs feature a high-temperature-rated neodymium magnet that captures ferrous particles for added protection.
