Question:
I did review your QandA but still not sure. I have a Curt round bar 10k/1000TW WDH and want to change bars for a smaller 500TW trailer. Beside the Curt capacity label on the head assy, the only ID I can find is on the bars which is 20/D03. The bar diameter is 1 3/8. What Curt bar I can use and I hope you stock them?

Hey Richard, welcome back! It sounds like you have a Curt MV Weight Distribution System. The 600 lbs TW item # C17071 is the lowest capacity replacement spring bar available for the Curt MV systems. It will work with 500 lbs - 600 lbs tongue weights.
The Curt item # C17071 spring bar is sold individually. We have a few of them in stock (01/26/2026).
