PML’s bolt-on replacement front differential cover is an aftermarket differential cover designed to fit Ram 2500 and 3500 trucks.
The differential cover fits the truck’s 12-bolt axle and is designed as an aftermarket option to improve fuel mileage. It's made of sand cast aluminum and has a low profile for better clearance because of reported clearance issues with steering, U-bolts and the suspension.
Fins on the lower part of the differential, where the fluid collects, aid in heat dissipation and cooling. PML designs and manufactures specialty automotive products including differential covers, transmission pans, valve covers and other products.
