One of the few mistakes some new owners do make, is not kmwoing how to differentiate a 3rd Gen OEM steps from that of a 4th Gen. There isn't much of a difference but the little difference there is, makes the 3rd Gen steps not compatible with a 4th Gen Tacoma. For 3rd Gen steps, the rail mounts horizontally to the ground. The steps for 24+ are angled to the rocker panel and the steps are mounted to the bottom rail with plastic side covers. Shared a photo of both the 3rd Gen side steps and that of a 4th Gen so owners can be able to spot and tell the difference. 3rd Gen 4th Gen

For those wondering, Toyota did give us a lot of what we asked for in this new truck. One crazy important feature, the 9.5" rear axle. This axle is nearly as big as a Dana 60, only .25" smaller. Naturally, they are super strong. You could technically run a 40" tire with relatively little issues. My plan is to run 37s bare minimum in the next few months, and 40s only if I decide to throw it on portals. But I'm beyond stoked on the beefier rear end. Hopefully the front can keep up! The 3rd Gen had a max size of 8.75". While still a good size, these new ones are much better.
