They would wake your truck up quite a bit. To do 4k's you also need 60# valve springs (on the exhaust side at the least), which you don't need for 3k springs.

Yeah, you do. If you don't run them you run the risk of floating a valve and doing some damage.

You do not NEED 60#s. I don't have them in my truck, but I know how to watch a tach. If you plan on keeping it under 3200, stock springs will do.

Well if you're going to keep it under 3200, you might as well use 3k springs. Plus that's a lot of faith you have if you're using a stock tach.
