T-17
I'm happy with the T-17 TJM I purchased through Steve at Sonoran Steel for our 2004 Tacoma. I also have a T-17 on my 1987 4runner. While the two bumpers look alike they are significantly different. Older T-17's are thinner and lighter and the "ears" that extend back towards the front tires bolt on. New T-17s, at least for the Tacomas, are thicker and heavier (but still lighter than many other bumpers) and the ears are part of the complete bumper. While I liked the light weight of the older bumper on the 4runner, overall I think the new bumper is better. I would not use a high lift on the ear, but I have worked a high lift into the vent holes under the front channel. I also think that you could jack via the opening for the winch cable if you wanted. The problem being that it is a high point and centrally located. With a 48" hi-lift you might not get as much lift as you'd want. I prefer to use the hi-lift on my sliders or on the rear bumper. I actually get the best lift with one of the adapters allowing the hi-lift to attach to a wheel - no suspension sag.
If you mount a Warn M8000 the bumper accepts it well, but the newer models don't have the access hole for the clutch engagement of the winch as perfectly positioned as the old bumpers. I find it easy to reach up and behind to get access to the lever, but if you were stuck to the frame in mud that might be a bother.
If you decide to go for the T-17 make sure you get the newer model with the one-piece construction rather than the bolt on ears, unless you prefer the extra light weight of the older style.
