standard springs,.check your spid label for the rate as there are 4-5 different rated springs,. if the ball joint takes the bigger nut its 5/8ths,.
but i doubt it,.,.check the joints for wear first,.no need to change anything that is not worn,..some folks change stuff just for the sake of having new everything,. but in my opinion thats a waste of money,.
don't put the cheap centrlink on it'll wear real quick as will the idler arm,. step up for these two pieces and buy moog problem solvers,.new centre link and idler and a couple of decent front shocks, and she'll feel like new,.
