I was in the same boat, I was leaning towards the Icon kit. I went on a 80's ride here in Colorado and was able to ride in both and I could not believe the difference. Both trucks were set up basically the same and had 35" tires. I rode the same piece of track since I wanted to really see the difference before I bought my lift. The ride on the highway was shocking after I bought my kit. I cant believe how smooth it rides on road.I get that the Slinky kit rides great, but I wonder has anyone been on a trail where there were rigs with both the ICON and Slinky suspensions? How does the ICON kit ride on the trail compared to the Slinky? Is there anyone with actual experience with both and not just keyboard racing?
Both are "designed for 35s" and both use dual rate set ups.
For comparable shocks, ICON kit runs a $1000 less. The ICON kit is designed for maximum travel with stock bump stops. The Slinky kit extends the bumpers stops to run a slightly longer shock, giving another 1-2" of droop.
Given ICONs reputation, I would have guessed that it would handle speed better than Slinky, but the Slinky guys say that it handles great so I'll take their word for it.
I am looking seriously at both kits. Right now my impression is that they are both similar quality. I want the one that swallow oscillations the best and smooth out the trail as much as possible. Based on the paper specs, I would lean towards ICON. But the Slinky kit keeps getting rave reviews and a cult like following by those that have ridden it. So has anyone experienced both?
