Are Sidewinders With 19k or 21k Capacities Available?  

Question:

Expert Reply:

There is a Sidewinder with a 20,000 lb capacity but not a 19K or 21K capacity. You will need to know the model number of your current pin box in order to find the correct fit.

Sidewinder # RP34FR replaces Lippert 0719, 1621 and 1621HD, Fabex 663 and 665, as well as M&M 663 and 665 pin boxes.

I have added a link to a help article on Sidewinders for you to take a look at as well.
