If the company is ProSpeed Lucky8 can source them for you. Just give them a call/email.

I've found options from Prospeed, APT, and Wildbear but none will ship to US. My lower control arm skids are Prospeed and I got them through Lucky 8 but the compressor skid is unobtanium, just like the Prospeed roof racks.
The sliders I have my eye on are the tactical 4x4 ones, heavy and expensive though. Some of the prospeed stuff is super fancy, like their under belly and rear diff armor, but I suspect the market for the lr4 is drying up.
I'm a fan of the Tactical sliders. They hold up very well on the trail.

The Tactical sliders are great. I have been using them for years and they hold up well, also act as bash guards / sill protectors, look great, and you can even jack from them.
Only problem down there (and with all these steel accessories) is the rust....

Dear @BigBriDogGuy
Great thread and excellent topic - so I am resurrecting / stealing this thread.
I am doing a rebuild (almost a complete overhaul) on my 2010 LR4 HSE (HD) with 90,000 miles (some hard).
We have reassembled the entire engine...and she lives!
We are nowhere near done but the fact that the engine has turned over means we haven't completely destroyed the truck and are likely to get through this build. Very exciting (and a relief).
That said, in approaching this build, I basically took @itsaguything approach: we didn't radically modify anything and I am mostly using stock / OEM. In fact, I have had to be obsessive in sourcing parts due to the superabundance of crap parts (everywhere).
There are things I would totally like to do, like completely change the exhaust manifolds and straight pipe the exhaust with bigger / larger pipes. But that is illegal and there is not enough room down there to really do much with the manifolds (and as pointed out - there is no aftermarket for these trucks so new exhaust manifolds would have to be custom made...yikes!)
Or put 35 inch by 12.5 inch Mikey Thompson tires. They would be very cool and look really tough. But that would require huge modifications to the frame and wheel wells as well as SIGNIFICANTLY decrease off and on road performance (i.e. power). So super cool...and super stupid (at the same time).
Basically, without making radical redesign decisions (which will seriously compromise something else)...I don't know what one can really do. I suppose there is a way to re-tune the engine and one could always redo the exhaust or something...but without tearing out all kinds of stuff (which will screw everything else up) like ECU's, I don't feel that the gain is worth the pain.
However, like folks said, consistent maintenance, attention to details on parts and looking for OEM (or better) parts will likely give you longer running times and therefore overall better lifespan. For example, I installed an "improved" vacuum pump from the original as well as the new chains and tensioners / guides (which have the metal parts which are supposed to wear longer). These aren't really modifications, however, as they are really just upgrades to the OEM components which were factory installed.
So I don't have great advice as to upgrades themselves but can testify that these trucks can continue to perform (probably for a really long time) if one keeps up with ALL maintenance items and uses the best quality fluids/lubricants and parts.
Perhaps others have similar experiences or new insights -

I think this is still a fun threat and things to think about, even though I recommended caution.
Following up with your idea, if one were to through caution to the wind, are a few crazy ideas I have had over the years (and I am sure I am not alone).
The first is power-train: the engine. I have the V8 and one of the fantasy items out there is the 5.0L supercharged (Jaguar or Range Rover Sport) engine. Our very own @Tapps33 is doing this, if I understand correctly, so he would be the man to speak with about this "great idea" -

Very cool and this has also been done in a shop in Colorado (Roadside Works) -
So if you want increased performance - one would certainly start there!
This is not for me, however, as my truck is really more of an off-road vehicle (which does a lot of highway, however) and my daily driver.
But a 700hp LR4 is definitely cool.

Project Dark Knight Rising
Well, it's officially begun....or rather continued from a few years ago. Long story even longer, I've dreamed of swapping the Supercharged 5.0 AJ133 into my LR4. Fast forward what I believe has been at least 4 years and 3 moves and now I'm moving again and will be stuck in an apartment with...

If the engine were the first thing to upgrade, the next would have to be the cooling system.
Unfortunately, there don't seem to be any aftermarket upgrades out there, so anything done would be (I think) a one-off, custom job. There are a number of companies out there that do custom radiators and inter-coolers, which could be used on the LR4 (with a lot of work but I think very doable).
I would add into this category (cooling system upgrades) things like electric fans, heavy-duty water pump, and silicon or stainless steel coolant pipes. I don't know of anyone who has done these kinds of modifications, or even any companies that offer products in this domain specifically for the LR4. There is one that apparently does LR4 stainless steel cooling pipes
https://www.partmasterhub.com/produ...mR5iUKEZlGYtTkoJ7Dv8jisizjgSdwxdG8ISb1C64xmai
It could all be fabricated...but that is a lot of customized artistry (and certainly way out of my league). Some very high-end shops build their own specialized and customized components like stainless steel piping for their truck builds (I am thinking of Mahker in the UK as an example): but that is expensive. Very, very.
As much as I think about this and even like the idea...I have three big criticisms (and why I am not pursuing this).
The first is: who would work on this stuff? You would have to do all the work yourself (or the shop which built it). Otherwise you would need a very brave (and trustworthy) Indy.
The second is: where / how would you get parts? I always imagine myself driving the highway on a road trip and the radiator blows (starts leaking). A custom radiator with all custom pipes would require someone to either weld the radiator back / fix the leak (good luck with that) or for whoever made the custom radiator to make a new one and send it to you. In other words...no one can stock that stuff and turn-around times for repairs will be complex and probably very long. This calculation, of course, could drastically change in ~10 years if and when we can't get replacement parts (although the DISCO 2 is still going strong).
Finally, I cannot quantify what kind of performance / enhancement such "improvements" would actually have. For example, as troublesome as my cooling system has been (I am now on my fourth coolant pump) - the system cools very well and works effectively when everything is functioning properly (which it normally does). Even in Extreme environments (and I am talking EXTREME hot or cold). The real issue with the cooling system is that it is simply too big and too complicated. Adding larger / more efficient radiators, bigger / better fans, way cooler piping, or even a bigger / better water pump (much needed) won't fundamentally change the engine design...which I think is where our problem really lies.
But always fun to think through these ideas - and I certainly welcome folks thoughts (and comments / criticism)!
