Not sure, I'll have to measure. I do know that there is plenty of adjustment either way.
You guys are absolutely right, it was not my intention to directly compare the two. The op said icons don't provide lift, my comment was directed towards that. With both Radflo 2.0 and Icon 2.5, I was able to obtain the same lift amount, and it happens to be that the icon didn't require any adjustment.
I had issues with the Radflo and have read about numerous others having issues as well. Even at preset height, the icons ride much better (although subjective and still not an apples to apples comparison). The icons have been great, no complaints at all with them. With the black Friday/cyber Monday promotions, I'd go with icon personally. I just never was impressed with the Radflo, both the shocks and customer service.
