Description
Heavy-Duty Aluminum Rear Differential Cover (Flat Back) for 2001-2019 GM/RAM 2500 11.5"-14 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, resulting in reduced efficiency and compromised traction control. Cast from high-grade A356.0-T6 aluminum alloy, this flat back differential cover adds .75 quart of fluid capacity and features half-inch external cooling fins for long-lasting heat management and performance. Built-in windage scrapers inside the PPE cover ensure precise fluid distribution around the gears.
