As it has been said, you dont NEED adjustable arms but dont drive it hard and go and stock up on Uni's for that tail shaft. You dont need a sye to run 2" lift but you guys seemed to get that.
I believe you should get them as it helps to get them uni's straight, thats why people get a sye, so why half do the job, it can cost you in the long run.
