Interesting...thanks all. Seems they are pretty new to the big truck category.
@boogielander, I am not sure they compare to the 5100's. I would think maybe something more higher end as they are $400 ea for the front and $300 ea for the rears. Their full lift kit for the DS Ram with UCR's, springs, shocks and sway bar links is $3000. I would think maybe Fox or Icon's perhaps? Do you think they are in the same class as other kits that are around $3000?
performance wise they are right in between 5100 (on the low end) to Icons (on the higher end, not that icons are good or anything. they're overly expensive unreliable trash that I've seen and heard too many failures of). They are nowhere near Fox or King in terms of performance.
pricing wise as you've mentioned they are up there. HOWEVER, I would still choose these over 5100s because they do hold more suspension fluid and rides more comfortable. Yes, they use "yoga mats" in their shocks (I'm glad you found Tinkerer's channel, it is very informative about IFS and he uses quite scientific methods to test things, but just know that he's not entirely accurate when it comes to solid axles in his other videos), but the truth is, even with yoga mats as "foam cells," they do ride a lot better than 5100s when going down the trail.
However, it seems like for DT they only offer front and rear shocks, and UCA. No spring, sway bar links are included. My Fox 2.5 kit with Carli UCA, end links, and springs ended up costing me about $4K or so at cost, but that is well worth the price tag when I'm hitting the trail going 50-60MPH.
To answer your question if I think they are in the same class as other kits that are around $3000, i would say they are the only kit I can think of at this price. Kings paired with UCA and adjusters are over $4k, without adjusters are about $3600 without rear springs and end links. My Fox at MSRP is over $5k. I do think Ironman is the perfect middle ground here if your budget is limited $3k budget. However, if you can save up more then I'd say go King or Fox, and make sure you get the kit with adjusters. You'll thank me later when you hit the trails.
Oh, just know this: ironman 4x4 has deals quite often. Last year they had a lot of 25% off sales. Right now they are running 10% off with free air compressor.
