Hey David, from previous customers of ours who have the same 2020 Keystone Raptor 424 we have determined that your pin box style is the Lippert 1621 which means for a Gen-Y gooseneck adapter you'd want the #GY58GR that you referenced.…

Trailer wheel bearings are specific to the spindle that is installed on the axle that is on your trailer. You will need to safely support the trailer, remove the wheel and tire, remove the grease cap, remove the cotter pin and washer that secures…

After you've packed the bearings and assembled everything, carefully slide the hub assembly onto the spindle and install the outer bearing. Install the spindle and tang washer and run the spindle nut down finger tight, then rotate the…
