Funtion: The differential girdle cover makes the rear end assembly srtonger, improves rear end life and durability, dissipates heat faster, and the extra fluid capacity allows for longer change intervals
Attention: This cover does NOT have fill hole/plug. Will NOT work for 2007 and newer 8.6" differentials that require a fill plug in the cover, these require M8x1.25 Metric bolts. This cover will usually not fit front truck differentials. Please compare to your existing cover before ordering
