I absolutely loved this kit. Watched a neighbor install this on his 2011 RAM 1500. Really nice truck, but it fell to the infamous cam lobe disappearing act. Tried telling him what his issue was, but he’s the know it all keyboard warrior type that has been there and done that. Can’t really say anything without him interrupting and telling you how wrong you are, just to be followed up with some war story about how he’s done this or that a billion times and how everyone else is wrong. Tried telling him his tapping noise was a bad lobe and lifter, but he assured me I didn’t know what I was talking about, and further stated hydraulic roller lifters never fail. A few weeks later, he then tells everyone that the oil change business that done his oil changes ruined his engine. And in no way would pay the outrageous prices local shops quoted him for the repairs. He then brings up how he spent a fraction of what everyone else quoted him for parts. Well…. I tried warning him. Oh my gawd the look on his face when the truck first roared to life, shortly followed by the most spectacular engine lifter noise ever! Especially as it warmed up. Again, I tried warning him. He assured me again that I didn’t know anything about what I was talking about. No one would sell absolute junk like this cam kit, because no one would buy it. If anyone could deserve buying this junk, it’s definitely him.
