Five (5) year warranty, with five (5) years more for a fee. No maintenance is correct. We are sure this has some down the road need and we would feel them like other wheels. Nitro is not a UFP system, and those axles are not always the same brand. The price tag for that axle as we understand it is about 60% the cost of a BCB axle and many other OEM products follow that pattern. Made in China vs. Made in San Marcos, CA also. There are other products that are the same in a Nitro, but they chince a buck where they can and greatly on the trailers. Just so others understand they are a different brand.Last edited by Bass Cat Boats on March 12th, 2011, 3:18 pm, edited 1 time in total.
