Our new patented Ram-Air rear diff cover fits 1985-2020 Ford Sterling 12-bolt axles with 10.25/10.5 ring gear. Not only does it make filling and draining easier with angled fill-port and magnetic drain plug, but it features a sight glass with contrast screen so you can see the oil level even if it’s clear! And for those who want to keep an eye on differential temps, it has a 1/8″ NPT port for installing a temp sensor. However, the real benefit is its ability to outcool the stock stamped steel cover and all flat-back aftermarket covers. And, you can order it with 4 quarts of AMSOIL INC. Severe Gear Oil.
