Well it may not have been worded right, but if he don't know if it has heavy duty springs I figured that would tell me if they will work for my fat ***.
FYI, These are great shocks--a vast improvement over the oem air shocks. The preload is very easy to set up (twist the top caps on either shock with your hands, there are grooves in the body to mark position) I have a set of 12.5" 430's mounted on my '16 Streetglide. I previously tried Ohlins and Harley Premium Adjustables. Price wasn't an issue. I'm set with the 430's.
