what else do i need

ok i just got my rims and tires, running cooper discovery a/t 265/75/15's on AR wheels. and i ordered a RC 3" full spring pack lift. what else do i need for everything to work right. I know i need an adjustable trackbar so if anyone has one for sale please shoot me a message. I am wondering about brake lines, and bump stops... the jeep won't ever see offroad except for gravel roads

For the Front Brake lines you should just be able to pull the bolt where the hard line and rubber lines meet and straiten the bend out of it and re-drill the whole and put in a new bolt and you'll be good there. For the back you can use a rear brake line from a Jeep Wrangler YJ (87-95) and everything will go together and bolt back on the axle and you'll have plenty of brake line there.
