Description
Improve the durability of your GM truck's rear differential with a PML Differential Cover. Created specifically for AAM 11.5" differentials in GM trucks, this rear differential cover from PML ensures a precise fit, serving as a direct replacement for the stock cover. Constructed from heavy-duty cast aluminum, the PML Differential Cover guarantees exceptional durability and resilience. The design enhances both form and function, providing increased fluid capacity compared to the stock cover. This larger capacity facilitates improved heat dissipation, contributing to more efficient differential operation—critical for those navigating challenging terrains or towing heavy loads. The cover's finned structure maximizes surface area exposure to airflow, promoting superior cooling performance. Installation is straightforward, utilizing existing mounting points without the need for modifications. The package includes all necessary hardware, ensuring a hassle-free installation process. Additionally, the PML Differential Cover features a magnetic drain plug for easy fluid drainage during routine maintenance. The magnetic drain plug also captures metallic particles, preventing potential damage and ensuring a cleaner, more efficient differential system. Choose the PML Differential Cover for a solution that prioritizes quality and durability, ensuring a driving experience that exceeds expectations. ADDING A TAPPED HOLE FOR SENDING UNIT: If you want to add aftermarket components to your transmission, such as a temperature sensor, a magnetic drain plug, or a fluid level sensor, you will need to drill and tap the transmission pan to provide mounting points for these accessories. PML can drill and tap for a 1/8 NPT hole for a temperature-sending unit in the cover.
