Trailing arms and lower a arms

I am looking at upgrading my trailing arms and lower a arms. Hoping for feedback from other pro xp owners. Is there anything I should be looking for or staying away from? I like the look and price of the High Lifter components. I can’t really narrow down my riding preferences because it’s kind of all over the place. I ride dunes in the winter and rocks, mud, jeep trails, logging trails, and pavement in the not winter. Please share your thoughts/experiences.
Thank you!

I have replaced all of my suspension parts with stuff from L&W Fab. So far all of them have held up well to the abuse I have given them. I replaced the upper and lower A arms, rear trailing arms, radius rods, and tie rods. I also replaced the ball joints with some kryptonite ball joints.

If you haven't already wrecked them I would just get some skid plates. The fronts of course are already high clearance, and from what I noticed on my own machine high clearance really aren't necessary or helpful. (Edit, talking about rear trailing arms)
I planned to get some high clearance trailing arms eventually but just got some trail armor sliders for now. Looking at the scrapes on the sliders, the farther back you go, the less scrapes you get.. basically, the part that is raised up in a high clearance trailing arm is the least likely place to hit a rock anyway.

Take a look at this picture That's a two+ foot ledge. Notice the tires already hitting the ledge look at where the trailing arm is hitting, It's not where a high clearance trailing arm would help... 🤷

That picture explains nothing to the point you're trying to make.
You have to be the only person in the universe to argue against high clearance trailing arms not being effective.

And this comment you made is totally 100 % incorrect because the further back you get on the trailing arms, the more contact there will be because on stock trailing arms, the farther back they go, the lower to the ground they are thus decreasing ground clearance. Your comment here - ". Looking at the scrapes on the sliders, the farther back you go, the less scrapes you get.. basically, the part that is raised up in a high clearance trailing arm is the least likely place to hit a rock anyway. "

See if my 1st grade schematics make sense, if not, good luck and happy riding.

Good video to explain the benefits of HC trailing arms...

I'm not arguing against high clearance trailng arms, nor am I saying there isn't a benefit at all, just that, in my personal experience in the rocks, the benefit isn't enough to justify the price.
The funny thing is your second "illustration" is actually closer to the reality of stock trailing arms than the first.
If the trailing arms actually attached to the vehicle above the bottom of the skidplate and came out at a giant angle like your "stock" illustration, then yea, high clearance trailing arms would be more of a benefit.
But in reality, the trailing arms attach to the vehicle below the bottom of the skid plate, and are close to level, not at a giant angle like in your first illustration.
Take a look at the bottom of any standard trailing arm on a vehicle that gets used in the rocks. You will see that the majority of the damage to the arm or skid is in the red area, with significantly less damage in the blue area. I'm just talking about real world experience, not unrealistic pictures with square rocks.... 🤷

Sure, if you are replacing your arms with aftermarket you might as well go high clearance, but if you are in the fence about spending $500 replacing perfectly good stock arms with high clearance arms or just adding skids to the stock arms, the high clearance arms aren't as big a benefit as people would have you believe. That's all.

I don’t really have a horse in this race, but it’s an interesting debate. I have chosen not to go the high clearance route at this time, but I’m glad the options exist and if I had to replace the stock trailing arms for whatever reason, high clearance is the way I would go without a doubt. My rig has about 2000 miles on it, and within those miles it’s split between trails, where clearance is of absolutely no concern, and crawling. I did a week in Moab this summer, riding the typical big name trails and hitting many of the obstacles. Im not a double black diamond conqueror like some of the guys on the site, but I enjoy more technical, challenging riding and am not afraid to put a couple of scars on the tractor. It’s been bellied out and the rear arms dragged a number of times. Curiosity got the best of me so I snapped a picture of one of my arms. There are scrapes and gouges the entire length of the arm, some of which would be prevented by high clearance arms, and others not. In the essence of full disclosure, I’ve never felt that dragging a trailing arm has prevented me from overcoming an obstacle, but again I’m also not doing the absolute gnarliest trails/obstacles. It doesn’t settle the debate, but is a data point that someone can use to make the decision on what’s right for their ride (and riding style). It’s great to have options!
