Avslash- the TR bumper looks great on your 4. I've been going back and forth between the ARB and TR for a while.
Also, are you running 1.25" spacers with those LR3 wheels? I just put some LR3 10 spoke wheels with 1.25" spacers on my LR4 with some 285/65/18 Terra Grapplers I found for a great deal on CL, but the rubbing is pretty bad. Curious as to what your setup is and what the rubbing is like.
Yes, I am running the 1.25" Motorsport Tech spacers mentioned in Scott Brady's build thread.
With the 275/65R18 I get slight rubbing at just short of full lock on the TR rock sliders. This rubbing goes away once you hit full lock on the wheel. The frame horns have been cut off and welded over on my LR4, so they are no longer an issue. I predict that this size tire will not rub at all after a few thousand miles of wear on the new tires. There are no issues with control arm clearance.
I previously ran 265/65R18's. They would rub very slightly on the frame horns at full lock only. Just enough to leave a shiny spot on the outside edge of the frame horns. With the frame horns removed, or really, just persuaded a bit with a hammer, there would be no rubbing in that configuration on anything.
I strongly considered going to the Compomotive 18" wheels when installing the 275/65R18's. If my understanding is correct, those wheels would place the wheel/tire combo slightly more inboard than the Stock wheel/spacer configuration. I think this would address the rubbing on the TR rock sliders. My issue on that is strictly cost benefit. The wheels on my truck get beaten to holy hell and back when wheeling on rocky talus slope like trails in the mountains. At roughly $125.00 a pop over the internet, the stock LR3 18's are somewhat of a disposable item, the Compomotives at $400ish, not so much.
On the ARB vs. TR gear, it was a no brainer for me. I looked into the cost to get my hands on an ARB front/Rear bumper, and it was crazy expensive versus the TR gear, which provides the same, if not better, functionality. I prefer the look of the TR rear bumper, as well. Once TR gets their second swing arm to market, it should offer all the functionality of the ARB version, as well.
