  • Why is the Tilting/Folding Activation Different Between the Swagman Semi 2.0 and 4.0
    The names for the Swagman Semi can be a little confusing in that we tend to think that 4.0 would be an upgrade to 2.0.

If you would like to carry 4 bikes you can either purchase the add-on # S64699 separately or you could just go ahead and get the full 4-bike version # S64698-99. The Swagman 4.0...

  • Recommended Hitch Extender with Anti-Rattle Option for Spare Tire
    The Swagman Dispatch 2 Bike Platform Rack # S44FR is designed to give extra clearance since the closest part of the rack sits 12" away from your hitch pin hole. To see if you have spare tire clearance, just measure from the center of hitch pin hole to outer edge of spare tire. I attached an article below with instruction for checking clearance. From what I can see though, it looks like it will fit with your 20X10 inch spare,. However, if you find you need some extra space, you can use...
