I recently picked up a set of these from Adventure Motors in KC (the very last set of sliders they had!). Immediately took the t4r to moab / CO to see if i could bash the living F out of them. After Cinnamon, Ophir, White Rim/Potash Road, Fins n Things, and a bunch of random county roads, i can report that i barely scraped them maybe twice! next time I will attempt some more challenging obstacles.
They look pretty great, though. Downside is now i really need another inch or so of lift, if for no other reason than to keep everything visually proportional.
shoutout to Adventure Motors if you aren't already aware of them. They are incredibly knowledgeable and helpful/friendly. also if you are reading this forum, they are a must follow on IG for toyota/lexus thirst traps
