12V cheap performance upgrades

Yes you can go to 4k. I would suggest buying the 4k kit regardless. All you have to do is leave out 1 spring and it makes it a 3k. The only real supporting mod you need is 60lb valve springs. You could put the 3k springs in until you decide to get the 60lb springs then put in the last spring and make it a 4k.

Look in my sig to see whats done to my truck. And the thing is yes you can turn 4k with the springs but how often are you going to really pull that high. I know if i'm hammering down playing around i very rarely pull past 3k so don't see any reason to rev that high all the time. Not on a 290,xxx mile truck at least.
