I have the OEM port installed tube side steps. They work well as a step and do a good job of protecting from door dings. I do like the look of the new predator steps though...
IMHO - the predator steps are not great. I've seen many posts of the steps catching and breaking on terrain. Also I took a TRD Pro for a test drive with those installed. I am used to my '06 Sport OEM tube steps as a means for convenient access to the roof all along each side (i.e. rack or skybox). The predator steps are useless for this and only good as a "stagecoach" type step in the cab. The back ones don't even line up well with the rear passenger doors and are awkward. So yes they look cool but aren't very useful. Also the mount seemed weak on them, they may not have been bolted tightly but seemed to be a lot of give when stepping one them.
The tubes on my 06 sport are super solid. I am shopping for tube steps on my new 2018 TRD Pro and guy at the shop said the brackets on my '06 OE tube steps are super overkill and he didn't have anything aftermarket to rival that solid mount (they sell westin, amp, etc.) Now I am getting 2018 TRD Pro and am concerned I won't get steps as good as the OE ones on my '06 Sport.
