well the truck already has dual 6 inch stacks ran i dont just pull i would like to slowly build it into a pulling truck. i was going to have the fuel plate grinded down to a 0. but on the gov springs what should i go with 4k is what i have been told? idk much about them tho

 

welcome and 4k is a good spring it would be smart to get valve springs too just to ensure you dont float em

 

Thanks Do you know were i can buy the 4k springs i have looked around locally and cant find them is there a good internet site i can get them or is ebay trust worthy? and what valve springs do you recomend?
