Through the build up of my FJC, I've been kind of obsessed with ground clearance. I've been documenting the ground clearance as I put various mods on my rig. Now that I've been lucky enough to work with Bud of Budbuilt, I think I've achieved the most I possibly can and my quest for ground clearance is maxed out. Well, that is until I pull a Sol and tear the IFS off. However, that is a few years down the road.

Now for the pics through the years...

Unfortunately, I don't have a picture of the measurement dead stock. The first picture I took was when I put the OME lift on, 885/140 and 895/N71e with stock tires, 265/75/16's. As you can see, this put it right under 12.5" of ground clearance at the exhaust crossover pipe...

This would be considered "stage 2", measuring at the skid plate crossmember between the t-case/gas tank skids. At this stage, I also had the same lift as before but upgraded tires to 255/85/16's (33X10) which gave a slight increase over the stock tires. As you can see in the picture, the ground clearance is just over 12"...

Here is the "stage 3" pic measuring after I put the 35's on. At the same (although a bit bent up from my summer excursion on the Rubicon trail, Moab and Ouray) t-case/gas tank skid crossmember, I had just under 14" of ground clearance...

Now, with, as Bud so affectionately calls it, the "Tummy Tuck", we have entered "stage 4" and you can see that I have 17 3/4" of ground clearance....

Now, for what Bud has done and how he did it.

First, the new transmission crossmember he built up to replace the stock one he cut out with precision...

The belly is opened up with a clear view of the Inchworm Lefty, something I haven't seen for a long time due to my extended belly...

Here is the mocked up exhaust to be re-routed around the Lefty, above the frame rails, final exhaust pieces will be mandrel bent...

Shot of the driver's side cat, tucked up nicely above the new transmission crossover. Notice how it is "clam-shelled" from above and below, very stout...

The tranny crossmember mounting from below. What he did was trim off the stock piece in such a manner that he used it as the base for the new piece, genius. As you can see, bolt on application...

Getting everything tucked up above the frame rails gained 3 3/4" of ground clearance. So, with the Inchworm Lefty transfer case and Bud's newly fabricated transmission crossmember, Bud's re-bent skids, new skid plate crossmember, moving the exhaust, all told gives an effective increase in ground clearance similar to running tires that are 7.5" taller than the existing diameter.

Of course, going with that much taller tire would also increase the diff clearance, which this modification does not do. However, running that tall of a tire would also seriously increase the center of gravity to such a point that wouldn't be a positive change for the FJC.

Obviously, I could never modify my IFS FJC to go from 35's to 42+" tires, that is, unless I SAC it. Even then, running 42's is a HUGE jump in tire size when Sol and Amanda are running 37's on their SAC'd FJC's. That is why this mod is SO highly VALUABLE when it come to truly giving a dramatic change in off-road capabilities of the FJC.

I can't thank Bud enough for allowing me the privilege of being his guinea pig on this upgrade. He is great to work with and did an excellent job. I took it off-road this past Sat and didn't get a rattle, buzz or anything after beating it pretty well. I purposely took some "bad lines" in an effort to see/feel the difference between the last time I was on the trail (2 weekends ago) and this past Sat. I had the full weight of the rig on the new skids/crossmember and it hardly scratched the paint, let alone bend them at all.

I know that he has a great many ideas on how to make this a progressive upgrade so that someone with a stock transfer case can use his planned "clocking ring" to move it up as far as one can, then by using his planned exhaust routing kit, you can gain ground clearance using the new transmission crossmember and getting your skid plates re-bent to fit the new profile.

Bottom line, this is, in my NOT so humble opinion, probably one of the most valuable upgrades for the "serious" off-roader for the FJC. It might not be a huge advantage for doing 90mph on the deserts but once you get into any rocky and/or technical trails, having an extra 3.75" of ground clearance makes an AMAZING difference...

Just a quick shot of the new belly from the trail, thanks Bud...

Not sure how I got over here! You did a nice job with that.

The next step is a solid axle and really magnify what you've done underneath.
 
Looking good, I like your driver side cat skid better than mine. We left the cat in the stock location so the skid for it hangs below the frame rails. :frown:. Definitely going to change that now that I got the idea.

It is also amazing how much lower the stock tcase hangs than the lefty. Did Bud give you any timeframe/ideas on a clocking adapter? At the tranny cross member, I gained about 3.5" but at the tcase only about 1".

I can't offer any time frame for Bud. I do know that he was planning on catching up this week since spending the past week or more working on this for me. I'd send him an email and/or phone call and see what he has in the plans and/or worked up a time frame yet...
 
haha, i keep following you around Jerry!

Here is a youtube link of this belly skid in action.

Not a bad thing. Just wish you had the video showing me getting off of my "belly", making it through that section. In any event, it clearly held the weight of the rig on the new plates and crossmember. Like you said in the other thread, nice work Bud...
 
Like everyone else has said - looks great. But the $64k question is: What would you estimate you've spent to achieve these results?

Also, curious about clearance of diffs and shock mounts with your tires and rims? Have you measured these?

As I'm sure you know and as I referred to in the post, the FJC is limited in tire size, unless one is to do a SAC on it. The largest "functional" tire size that can be put on the FJC is a 35" tire. Therefore, there is a limit on how much change can be made at the front/rear diffs and shock mounts, etc.

Unless someone is willing to SAC an FJC (like a couple individuals that have been well documented already) and use portal axles, there is little that can be done to an IFS FJC to change the clearances you refer to. In both of the cases I've had the privilage to wheel with, both were running 37's so they gained another 1" of "true ground clearance" at the diffs with a SAC.

As to the cost, this took the cost of a new transmission crossmember, the labor to cut out the stock one and re-route the exhaust. Not that big of a hit in my book for the huge benefit of having a flat belly with an extra 3.75" of air below my rig.

Bud is offering a skid plate "trade-in/re-bend" program for those doing this upgrade, so a new set of skids don't need to be purchased (assuming you already own Bud's skids). I already had the Inchworm Lefty installed with the side benefit of it being that it tucks up nicely instead of the stock transfer case.

Once Bud develops the clocking ring for the stock transfer case, you would be able to do it w/o the cost of the Lefty, just won't have the same gain but can do a progressive change as I referred to in my original post.

I can't provide "hard" numbers on the cost. Being the first, things take time to get done and if I publicly posted the bottom line, it would be too easy for my lovely spouse to find out. Best way is to contact Bud at Budbuilt.com and he will be able to tell you what it would cost for your application...

LOL! It was fun and we definitely were in good company. Nice job on flattening out your belly. BTW, the "Yellow Turtle" nickname fits so well.

Thanks, Bud did a great job on it. I keep looking under it and there is nothing there. Don't know how much difference it will make but I'm hoping to make the big drive again this summer but the wife will come this time...

Are you planning on Rubithon 2009?

Of course he is!!!

It is the plan at this point at least. I'm hoping to make another generous donation to the big oil companies but only if the price per gallon can get back up to $4 again.

I know I have at least one other FJC from SC that is interested and I'm working on a few more. I'd like to see a line of at least 20 FJC's for Ron to have to "short rope" through the trails like he (Robbie and Woody) did for us this past event...

Cool! I plan on going again.
