Allison pressure spring and shim.

Reading the instructions for Mike's pressure spring using the shim and spring causes faster pump and ring wear occur. My question is how fast will this occur and what all must be replaced to repair it.

Depends on how much you race the truck. The rings don't wear; it's the front rotating assembly that will get ring grooved. It will take a lot of abuse to make that happen.

So if mainly a daily driver it would take a while? Is the way to repair the rotating assembly or just replace?

Replace.
