I have been on a long jurney trying to get a suspension that actually works well on the road & the trail. It has been a big learning curve on what just works & work a lot better. I have used several products & brands of shocks & coils to get me here where I am at today.
I have had two sets of Old Man Emu coils springs and have found them to be good with drivability and handling on/off road, but not great. Again good but not great. I want a suspension that performs great on & off road. I have learnd about dual rate coils & have found several manufacturers that offer them for my 80 series rig. OME, Icon & Redline Slinky. All three have great attributes but one stands out to me for the longest suspension travel is the Slinky long travel coils. These longer coils allow my rig to have longer shocks which means my tire goes further down, has more traction & control.
Let me explain dual rate, these coils have a soft plush & firm stable feel. While just going down the road it has a soft feel but just under that is a strong firm stable heavier coil. Two coils in one, a cake & eat it situation... just simply awesome. Here is a pic of both my single rate OME & my new Slinky dual rate coils, note how much taller the silver coils are.
