Fit perfect on a 2001 2500hd vortec 6.0. I have always had a valve ticking at initial startup but after installing this it gets so much oil that it doesn't do that anymore. Has great pressure also. Very happy with this pump. It's a tough job to change out but worth it. I recommend get the correct harmonic balancer puller and installer. I tried to get by with what I had but ended up having to get the vehicle specific tools.

Just installed this onto my LQ4 which is going into a Silverado. People rave about these eliminating lifter tick! The quality is exceptional!!!

I have not yet installed this particular oil pump but having used them in the past I can say they are high quality and being made in the USA you won’t be worried a hundred miles from home in your hot rod about losing oil pressure.

I would recommend this oil pump as a replacement for the original factory parts for better oil pressure
