Bad balancer

I believe the SLP pulley is a relabeled ASP pulley. Many have went through reinstalling the stock pulley to find out that wasn't their problem.
PS:: just a note did install of ASP on son's 5.3, it ran good for about one year then tbe inter and outer hub begain to come apart ( rubber was comming out ) ASP gave us anew one and now about one year latter no problems
one other note SLP did allow me 1/2 price of pulley on something else from their stock
good luck Johnny

Yes there were audible noises. It sounded like rushing water. I put the stock one on last friday all the noises and the KR have disappeared. The SLP pulley wasnt doing its job as a harmonic damper and what i was hearing was my crank ringing. If it wouldve continued over a longer period of time it prolly wouldve blew the engine. Everythig is fine now with the stock pulley back on.
I too wasted bucko dollars trying to track this issue down to find out it was the pulley all along. So now I will wait til the first of the year for the new pulleys to come out because the ASP needs machining when used in conjunction with the rollermaster timing chain and gear.
