After looking for an aftermarket rack for my 2006 Yamaha Wolverine 450 4x4 and only finding one small, expensive option I decided to build my own. Pictures are from start to finish. The center section is recessed 2 inches for hauling coolers, bulldozer batteries, etc. It also minimizes the need for strapping stuff down. It has 4 I-bolts at the corners and grade 8 hardware.
