My opinion from just looking at them, they won't protect your tub the way sliders that bolt to the frame do and I highly doubt you can use a hilift on them. You might but I'd guess they'll buckle under the weight of the jeep.
Agree. I wouldn't try and high lift against a piece of aluminum. For a little over $300 you can get PSC Rocker Knockers and gain sliders out of the deal. They tie to the tub and body mounts making for a solid jacking spot.
