Holman’s new scalloped wind deflector design is proven to cut wind noise by more than half. The Pro Rack Leg & Bar kits include this wind deflector, but you may need this part to retrofit to an older Pro II truck w/ cap, service body, or platform rack or to replace on your PRO truck w/ cap, service body, or platform rack. This wind deflector bolts to the front crossbar and can be positioned to optimally deflect wind up over the cab. Especially recommended when standard length racks are mounted on extended cab trucks.
