Have had our KK-460 since 2007 so it's well out of warranty. Had one fender crack around the rivets last year. Called Demco, they had me send pictures. Then they asked for my shipping address. A few days later two new fenders arrived at NO CHARGE even though there was no warranty. I had to change both as the new fenders were wider and looked like they would accept a 15" tire rather than the 14's I have. Earlier they had sent me a spring stop that was needed by DP's with engine/exhaust brakes, again, no charge.
