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.

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.

It fits great in my 2002 5.3. Product was shipped professionally, really happy about that. Comes with extra gaskets too. You can’t go wrong buying this kit

This is the best street pump I've ever used. Instant pressure and very reliable. A must have whenever you're building an LS or just want it to last.

My oil pressure jumped up 20 psi and almost reaches 80 psi while accelerating! No more ticking from my lifter in the morning either so I’m so glad I invested in it! I definitely recommend it.

I have not installed this unit yet but I am not concerned about its performance. Being a former engine builder and having owned a repair shop I have no doubts this will perform fine from previous experience. Don't expect miracles if you have a badly worn engine though.

Have not used it as yet but it's just what the doctor ordered.
