I put 302/325 Dobinsons lift and Dirt King BJ UCAs on my 4runner and have been thrilled with the ride. It’s definitely not oversprung like my OME on my 3ed gen snd the nose dive when braking is gone. It’s super comfortable on and off road.
With Dobinsons Dirt Kings and FN Six Shooter wheels I had only minor rubbing on the fender liner with E rated 285-70-17s. Quick 15 minute fix.
Good choice on C4 sliders. Mine have been awesome. We put them on right after we bought the 4Runner in 2016. The filler plates are perfect steps for kids and getting up to the rack. No regrets on the sliders. Definitely saved my rockers from damage and door dings in parking lots.
I was considering kings but I wanted a setup that wasn’t $3k just for suspension and requires rebuild maintenance. Icon and King are definitely industry leaders with their products they sell, theres no denying that. For me it just wasn’t something I was willing to commit to at this time. Maybe one day though. From what I read people are getting a ton of miles out of their Dobinsons with ride comfort that I was looking for at the price ($860) I wanted to pay. Part of my decision making was due to watching a few front runner outfitters vids on YouTube. They have some good content out that talks about how they go through their decision making processes for parts they put on their rigs.
