If you haven't already, try quoting this at SendCutSend as they have by far the best pricing I've found for smaller sheetmetal components like this.

I actually ordered one from SendCutSend a few days ago! Should be here in a few days. I need at least 1 skid plate to design the brackets that connect to the bumper bar.
 
I've ordered a ton of stuff from SendCutSend for building my CAD-designed metal deck railings. It's super-clean, laser cut metal, and all of the mill scale is ground off before you even get it. There are multiple local shops here that have plasma tables, but they usually have 2-3 week backlogs, and I know the metal will be some rusty sheet that's been sitting outside for months, covered with mill scale, with rough cuts and plasma beads all over it. Only cleanup with the SCS metal is taking off the sharp edges that can cut your fingers.

There are 2 skid plates extenders that I am aware of. NYTOP which is 1/4" 5052 aluminum at $333. The one I have is 10 gauge stainless steel from Go North Offroad and meets all my needs. Cost was $168 delivered. Not sure the NYTOP adds anything that the Go North does, would have to be a rare angle to hit it bad enough to cause any damage.

I don't worry about the windshield washer reservoir, if I smack it and loose fluid I can still get out of the woods. And a replacement is ~$125. There are replacement relocation kits out there but run well over $300. If you have a really high clearance bumper you don't have to look at it anymore.

The water in the air intake issue after cutting the bumper and liner is real and can hydrolock your engine destroying it. It is not unique to the GX T4Runners and Tacos have the same issues. Especially with a viper cut on a T4R. A snorkel helps with that but not an option for those of us in the Northwoods where it would get ripped off. And not everyone wants to wear a snorkel.

Personally I feel solving the water ingestion issue on liner cuts would be a best seller and across several platforms. Solve that and you would likely be so busy you would have a new full time job. My 2 cents anyhow and worth what you paid for it!



Oh yeah... Going back to serial ports and hardware dongles. And double floppy drives one that had the lic (license) on boot. I don't miss those days. Not sure a sitewide dedicated license server is any better but been a couple of decades since I've had to run and manage lic servers.



1974 Hey you are older than I thought! My 50th HS Class Reunion is next year. 1974 is around the time I got my first parallel edge board and no longer had to use a T square.

BTW it isn't called a ruler it is called a scale ;)
Actually my 50 year reunion is coming up in 2027. My paper, pencil and "scale" ;) was during my high school. I had 4 years of drafting classes.
Thanks for the correction. Don't use scales often unless I'm reverse engineering or to fit something. But then I'm usually using my digital calipers.
Plus I'd just confuse my wife if I asked if she seen my scale. She'd come up to me with the bathroom scale ask why I need to weight myself.

Wow! Very nice! I'll have to remember Sendcutsend!
 
I was totally going to design something like this as I recently trimmed my bumper. Still may as I have a few ideas I want to try but similar concept of using thick ALU and supporting from the front slide and bumper bar. Just gotta wait for the snow and ice to melt in my driveway before I roll around under the GX to take measurements.

I'm interested to see how it comes out but know from experience that Version 1 could often use a design tweak or two. If you don't get 10 people to commit, consider biting the bullet on having 1 made (I know it's expensive), refine the design, and you'll have some documentation to show the next 10 people how it looks and functions.

I've been using Autodesk Fusion 360 for my home needs and it took a little getting used to but I really like it now. They have a personal version that allows up to 10 parts to be active at once, but it's not for commercial use, i.e. you can't sell what you design.

It's licensed in a subscription model like almost everything these days and I went ahead and purchased a 1 year subscription for $340 when they had a 50% off sale. Not cheap but compared to SolidWorks, it's a bargain. Compared to the Siemens NX and ANSYS licenses that I use at work, Fusion is basically free.


I'll give you that SolidWorks is the most intuitive of the old guard, but the best? It depends on your use case.

We exclusively used SolidWorks at work for more than a decade but found that it was downright atrocious with large, complex assemblies. Once we started getting to 100's and 1000's to >10,000 parts in a top level machine assembly, and lots of sheetmetal components, rebuild times and crashes became intolerable. Some of their mitigations such as lightweight parts, Large Assembly Mode, and Large Design Review can help, but design the same thing in NX and you'll wonder why SolidWorks in 2025 is still such a dog.
I'll concede that for large 4 or 5 digit number of parts in assemblies, even with my Xeox, 64 gb ram, 32 gb on my RTX Nivida graphics card, I'd probably get glacier speeds. In the medical device industry if we have more than 30 to 50 components to an assembly, that's a lot, unless it's electrical componets like scanning machines, body function monitors, etc. then it might get up to a couple hunderd parts.
Curious, if you can say, what industry are you in for such large assemblies, automotive, aerospace or?
 
I do think there is a market for this for people doing intermediate clearancing of a GX.

Back when I did my bumper trim, I was not comfortable with the exposure of the AC condenser to bouncing rocks and such, and a friend made a cover plate for that area. It is some kind of hardened stainless steel he had laying around. I still have it if somebody wants it.

Product development of large, web-fed ink jet presses and their various ancillary systems. Printing from 50” diameter, 20-23” wide rolls of paper at up to 738 ft/min.

Nothing compared to a large web offset press in both size (and speed) but each press is the size of a few GX’s stringed end-to-end, and can stretch much longer depending on the pre/post processing equipment attached to it.

It’s much less glamorous than it might sound, which can probably be said about most engineering careers.
 
AC condenser skid is on its way so more photos of that design coming soon!

I was able to work on creating a plate to cover the windshield washer reservoir and associated components today. This is also the side the air intake resides.

This plate will utilize 2 factory mounting locations and 1 bracket.

Next up, the CAD work!
 
I’m thinking .125” thick 5052 aluminum! Just a blocker for water and debris.

A suggestion - make a break and bend up the trailing edge 90 degrees. Add a few holes and rivnuts and you'll have a support bracket for the trimmed fender liner as well as making it stiffer. I'd probably buy/make something similar that covers the entirety of the bottom of the bumper hole.

I'd also maybe bring in the same trailing edge so that it leaves some more room for larger tires. I know my 33s touch the trimmed fender liner sometimes but if the bracket pulls it forward without too much stretching then it'll help to keep it there.
 
Hi all!

Engineer with some extra time on his hands so I decided to attempt to create a skid plate extension for the GX460. Not really satisfied with what's currently being offered on the market, especially at the price.

I'm designing this based off a bumper cut GX460 with the lower brackets removed (my personal 2019). I'm going to design a bracket that will connect the skid to the bumper bar for those of us that cut those factory brackets off. But I'm also incorporating holes to line up with factory brackets if you retained them.

The other guys skid would run me $337 shipped to my door. I can easily shave $100 off that price with my design if I were to market it and it's still made of 1/4" 5052 Aluminum. I also made it to be 26" wide to provide full coverage. It would be around $237 shipped per skid if I got 10 people that wanted one.

Would anyone be interested in these if I ordered a batc

Totally agree, doesn’t need to be too thick. What do you think about having a flange or two to connect to the fender liner (above the plastic rivets) for stability and to hold the liner free of larger tires?

You beat me to it. Exactly this.

Thank you all for the suggestions!

I added a 1" flange taking the plate in a total of half an inch. The holes are 0.162 in diameter which will fit a 5/32 rivet. This will bring the fender line in some!

Just ordered both the bracket and plate. ETA in a week.

Well that was fast!

However.... that blocks your air intake and may be too much. If you look up the rear chamber, the one in front of the liner, at the top you will see the elbow that is the air intake for the air filter. So you have to be careful to not block too much air flow. There are a couple of cutouts in the liner, not sure if they are large enough for the amount of air required for the engine.

May have to make some cutouts with deflectors for water, or it just may work.

If you don't have an OBD monitor I would want to get one and set a baseline for the Mass Air Flow sensor (lb\min) and Intake Manifold pressure (PSI) first. Do a before and after comparison. I'd likely throw in Air Fuel ratio as well. And across the full range of the throttle. Several of us have OBDLink MX+ Fusion but there are others out there. You certainly want to get metrics though.

I think you are starting out on the right path!

What black trim moulding did you use around the edge post bumper cut?
Loving the designs, glad you have the time!

The intake can also pull air from the fender through the cowling - it's not fully sealed up top.

Factory bumper also has a panel covering that area!

With the bumper cut, that’s usually removed leaving the area exposed.

Yeah but not much air, we discussed that back in September. We both were looking at cowl induction intakes, never did find someone that did it on a 460.

A guy on TW has a full time job making and selling cowl induction kits for 2nd gen Tacos which is what I had. I still spend some time on TW. If someone finally comes out with one for the GX I'd give it some serious thought! His is $200 CDN which is a pretty decent price.

I have a vague recollection of that funky plastic piece but it is long gone on mine. As well as many others I'm sure!

Provided no CEL and errors I am very interested in this. Not in any hurry we have "hard water" here for a few more months yet. Drive on top of it, not through it LOL.
