Rear mud guards fell off.. twice.. lost em completely first time, company replaced them no problems. Found them the second time n actually drilled through mounts n put a nut n bolt on them this time n so far so good. The company should include that upgrade with nut n bolt. Front arm skid guard held up for three runs, n lost one.. didn't bother with contacting company again. These should be manufactured with a skinny washer and an imprint to let was sit flush n maybe they would have stayed.. customer service was great though..
