Control Arms by KSP PERFORMANCE. Details: The style of level or lift will determine how much height you will need to add to the front or rear. To level your vehicle, add a lift amount equivalent to the difference between front and rear heights. To lift your vehicle - while retaining the stock look, add the same lift amount to both front and rear. To level lift your vehicle, add the amount of lift you'd like for the front to the difference between front and rear stock heights and use this for your rear lift. For example: if your stock height for the front is 23" and rear is 26" to level - add 3" lift to the front or to lift all corners 2" - add 2" to both front and rear. Notes: All the zerks can fill in grease after some use (pre-greased when you get it) Do not torque the zerk too tight and It can turns to different directions(not must vertical)---the right and left zerks no need to the same direction. The ball joint could not fill any grease.
