Transformation!
As soon as I changed the gear oil in the front and rear differentials my old rusty truck suddenly tranformed into a brand new beast! All the rust disappeared, the horsepower jumped to over 10X what it was and the old vinyl upholstery was now luxurious leather!

Nice Product
Rec'd in about 3 days. Great packaging. Product looks great but just got installed on Front and Rear diffs 2018 Ram 3500. Tool for test drive after finish and seems great. Will be towing 24 ft Pontoon boat about 400 miles in desert heat to Lake Havasu so that will be the test and will update review after that. Im expecting zero issues. Fluid has great reviews
