Review: Great Gear Fluid without Breaking the Budget! - Valvoline is great rear-end fluid for my Ford 8.8. Added during a recent fluid and differential cover change. WIth the limited slip additive and Flexfill gear oil, my differential hooks up much better and is definitely smooth as butter. The gear oil bags/packaging are very useful but I still used a hand pump/hose to add back the new oil to the differential. Highly recommended for the health of your differential!
Review: Great design & product! - Perfect, used as a maintenance item on a 2019 Ram Rebel as the differential fluid on the truck needed limited slip additive. So far the fluid is doing its job with no leaks. I love how easy it is to fill the differential with the baggy design for the product, brilliant! Great value for the money!
