It looks like a good price for the pair. Thanks to Andy for spotting them.

“Willy’s front frame weights for the Agri-jeep / trenchers and even snow plows in great condition and can load for you ! If you have a new 2023 wrangler Willy’s sport the addition of just one of these weights to the back for traction this winter will make your new “Willy’s” 6.72% percent real Willy’s jeep and the envy of all your fellow “Willy’s” jeep compatriots ! Both weights will of course double the percentage but I must warn you that your head might explode with pride and I recommend just settling for the one ! Percentage will vary with make and model !”
