These Stainless Steel Bearing Buddy Protectors will fit most 4 or 5 lug bolt patterns. These are your best protection for your bearings and hubs. Each Bearing Buddy, when properly used creates 3psi of pressure which keeps water from being able to penetrate your hubs. These come with the Blue Auto Check Indicatior which makes it easy to know what the internal grease level is. These are Stainless Steel, NOT the cheap chrome.
