Out of the factory, the 2013-2018 Ram 3500 are impressive workhorses. There are a lot of demands put on them, and that leads to heat and wear. Stamped tin steel differential covers are nice for holding in oil for a time, but they really fall short in protecting your ring and pinion from heat, and debris.
Enter, well rather cover the front and rear differentials with BD's Differential Cover Pack. Cast Steel, with multiple heat dispersing vanes, the BD differential covers feature a magnetic drain plug as well to pull debris from gear oil to assit in cooling while pulling harmful debris and metal shavings away from the running gear promoting performance and long life.
