That is cool to see you have a larger battery than stock size. Based on what you said here, is there another larger battery that can fit here? Is the battery more heavy duty than this one you have installed?

Now that I have these auxiliary lights installed on my QX and they all work directly from my battery, I figure I need to start looking for a more heavy duty battery before I drain my current oem battery that was installed brand new 3 years ago. It may be coming to the end of its life soon, though I cannot tell yet as it seems to be performing flawlessly so far. But I am sure I will need to upgrade soon and I would like to make the sacrifice to buy the most powerful heavy duty one that can fit in the battery tray on our cars.

Do you know of any battery that is more powerful than this that you just installed that would fit on our QX? I may be interested in looking into maybe buying one some day down the road.
There is a larger size that will fit, it has even more capacity than the one I have now. I will find the size and post it for you.

I plan to buy it in the future and move this current battery to be the secondary battery behind the driver seat. I won't do that though until I start building the cabinet/drawer system.

I really dig the way the lights turned out for you. So, I was bored and decided to add some more lights to my rig just because. Now I have to keep this rig until atleast 250,000 miles before I can think of getting rid of it.

Here are a few pics or you can click on my link to see more of the pics on my thread on club Armada...

Looks cool. I still haven't even wired up the LED pod lights on my roof rack.

Group size 31 battery should fit, I am like 90% confident.

It's almost double the capacity of the stock group size 34 battery.

In the beginning of January I took a trip with WCORA to Death Valley. I was 30 minutes late to the start time and the group had already left. In a rush to catch up, I was going very fast, in excess of 60 to even 80mph at times over some rough terrain. As a result I bent a lower control arm in the rear, the Y62 platform has 2 lower control arms in the rear as mention before in my post about the airbags. I bent the one which holds the coil spring (and airbag), this control arm is the one which affects the toe.

Over the course of the day, it gradually got worse, to the point where I was unable to drive further because the vehicle was literally driving sideways LOL.

We were 2 hours from nearest town, and 4 hours from nearest junkyard (Las Vegas), a cool dude from our group rich gave us a ride to Vegas to get a new (used) control arm, we made it back out the next day and did a field repair and made it back home. Had alot of fun even though I didnt get to do the whole trip, the experience of breaking down in such a remote area and having to leave the vehicle undefended was scary but exciting at the same time. Rich is an amazing guy and actually lives full time out of his 4-Runner and travels America, he has countless great stories to tell.

So, in Australia they have Billet Aluminum LCA's to resolve this issue. I have been waiting like 5 months now just for springs to arrive from there so I really dont want to order LCA's now and wait.

Instead I am going to modify the factory LCA's to make them stronger. Brand new OEM LCA's are only like $40. One issue is the rubber bushing is not replacable, and also the area around the bushing can not be strengthened because the rubber will melt if welding anywhere near it.

Instead I will replace the bushing with a much stronger and replaceable poly urethane one, its also greaseable.

The next issue and greatest issue with the factory LCA's is that there is an area of significant weakness on the top of the LCA near the frame side mount. Because it is not boxed on the top, it can widen apart and bend. If this alone was boxed, I think it would be much stronger, so I will do that.

I am also going to combine 2 lower control arms into 1 by splitting one in half, using it as a shell to place over a complete LCA and then weld them together. This will effectively double the wall thickness from .125" to .25", which is pretty thick and should be plenty strong.

I think the pictures will explain what is going on, this is still a work in progress, I ran out of daylight today.

You can see how its sandwiched perfectly:
