so i'm looking at getting a clayton long arm kit with an adjustable trackbar... question is there a big diffrence getting the drop down bracket or would i be good with getting just the adjustable trackbar....

i have 4.5 inches of lift right now.. i MIGHT go bigger but it wouldn't be any bigger than 6 inches

 

You won't at 4.5 inches of lift but I am not sure at 6. But if you think you'll ever want to go back to stock height for some reason like to sell it then I'd recommend the drop bracket since you will have to drill out the track bar hole on the frame to a bigger size for the bar
