We recently learned that Ford implemented a running change in May to the inner frame brackets for 2019 Super Duty trucks. If you are installing a GNRK1117 on a 2019 Ford Super Duty and find that the truck doesn't have inner frame brackets, we have a supplemental kit GNXA817 which will provide the two side plates necessary for install.
Moving forward we will recommend the GNRK1116 for all 2019 Ford Super Duty Trucks. The GNRK1117 will still fit 2017-2018 Ford F-250 & F-350 4WD Trucks.
GNXA817 will be available through your distributor early next week, or through B&W now. This kit will be sent out at no charge to dealers installing a GNRK1117 in a 2019 Ford Super Duty without inner frame brackets.
