Made from UHMW material (ultra high molecular weight polyethylene). They simply screw into the forward bracket of our traction bars and elimante the metal on metal taping sounds caused by rough road conditions. We use two types of threads on our bump stops. Course thread and Fine thread. Both are 3/4. Please verify which thread type you need if purchasing for a set of traction bars you already have. If you are purchasing them along with a new set of traction bars we will install them for you.
