That means that Mavrik parts meet the exact same requirements as the name brands. You may think that paying premium prices means that you're getting safer parts, but you're really paying more for the name on the label. ReliabilityMavrik OEM-equivalent parts go through rigorous testing and must meet strict quality standards, many of them coming to us with industry-recognized certifications. All of our OEM-equivalent parts are backed by a 90-day return policy and an unbeatable 180-day warranty, so you can see Mavrik quality for yourself, risk free.Warranty protection You may have heard that using OEM equivalent parts voids the manufacturer warranty."
