That's not exactly a true statement. There is plenty of adjustability. You can turn the E-Clik dial to adjust shocks for either a softer or firmer ride. You can do just front, just rear, or both. In Pro mode you can adjust brakes, roll / pitch, tire size, and more.
Both systems work well, just depends on which way you want to go, IMO.
Just checking back into this conversation and good catch there.
With SDI, there is a lot of adjustability, as stated above and you have the addition of payload setting that you can adjust your rear if you are towing or carrying a heavy bedload.
SDI also revalve's your shocks and this makes a big difference. I drove my truck for about two weeks before I got the shocks rebuilt and while it was much better than OEM, the complete system works wonders together. And you can adjust your shocks while driving!! thats really awesome!
I considered the DCS sport, but honestly they self admittedly don't have a ton of off road experience. Sure they have done testing in Texas (they are based in Maryland I believe). SDI has been in the Southern California off-road industry for almost 30 years. (Watch Keep it Dirty SDI Shop tour on you tube) And that's where I drive, and why you see many more YOUTUBE videos of them out testing. Plus SDI is local to me if I have any issues.
So, if you drive a street queen the DCS is probably a great choice. IF you are an avid off roader and drive it daily, I think SDI is the way to go.
