No idea but they do lose you 2.5" of ground clearance on a stock TRD without any steps or whatever.
What this means is that you will be hitting the rock sliders chiefly because they are there not because they protect anything. We have completed 80 trails (dirt roads included) in the 4R and on all these I have had so far a grand total of 1 hit where I might have damaged the rocker panel had I not had sliders. All other hits were minor hits and minor dragging that only happened because the sliders were there.
And I only hit on that occasion because the presence of sliders made me too lazy to get out and look which I would have done without sliders.
In other words, are you sure you need sliders? If you need steps, then sure, better get step sliders as low hanging steps can be destroyed even on a moderate rated trail. But it takes a lot of rocks to threaten a 17" tall rocker and that's without any lift.
The other thing about the Shrock sliders for 5th gen is that they may be just strong enough but I would not call strength their forte. You absolutely must drill the hole required by the front leg of the pax side slider if you want to be able to take any serious hits. I actually had a second leg welded instead since it did not seem to me that the extra bolt underneath will suffice. I don't yet have an extra leg on the driver side because I can see that side a lot better, of course.
On the plus side, they have a fantastic finish, OEM-like quality, which is really why I got them. I did not want macho looking burly sliders. But the Shrock sure could have come with an extra leg in addition to the underframe wrapping.
In other words, it is TBD on whether going Shrock over my other finalist, the RCI step sliders, was a good call. They are good sliders, but not great. Someone at the dealership must have lifted the vehicle from the sliders during oil change because both have made minor contact with the rocker panels, definitely not from trail. Which means they are not strong enough even with the extra bolt underneath. I think the 3rd leg improved that: I lifted the entire right side on the front of the slider after adding the third leg without contact.
