Review on 🔧 ACDelco Professional 45K18022: Complete Front Camber Adjuster Bolt Kit with Hardware - Superior Adjustability and Easy Installation by John Brouillard

They are nickel plated and the screw is machined to have a flat edge for turning the cam. The nock has a flat edge. The originals are black nitrite coated and the cams are contoured for durability. This product is just a cheaper version of the original. OEM adjusters can be cleaned on the spoked wheel if rusted and put back into service if not bent or badly rusted. Each pack contains one regulator; You will need four together for both sides of the front.
