The jam nuts are zinc plated. The tie rod sleeves are iodized gold 6061-T6 aluminum drawn tubing for strength, durability, and precise fit. The hexagonal rods are made for "on the spot" quick refine adjustment. These are great for correcting negative camber - when the top of the wheel is tipped in towards the body. Camber is the tilt of the wheel along its vertical axis.
Running wider tires or car with lowering springs can cause this issue where your tires are wearing out on the inside. They are also great for older cars where the suspension tends to sag hence the wheel looks "spray out".To some degree, this is a good thing as it allows more of the tire tread to stay in contact with the ground during hard cornering. But if you have too much negative camber, which degrades cornering performance as well as hinders grip during hard acceleration. The camber kit can straighten the wheels by dialing out the negative camber, something you can't do with the stock suspension. They are also great for race days where changing from street tires to drag or race tires where the camber need to be adjusted on the spot.
You can manual dial the wheel in by adjusting the rod in or out. Like wise, if you want more negative camber, this kit can put the wheel further in, allowing more negative camber for those of you who would like to have the "tuck-in" and slammed look.These are great to pre-lube the rod ends, bolts, nuts and the aluminum piping before installation. A small drop is all you need to lube and waterproof the bolt, nuts and rod ends.
