look at the DBR truck for instance. its just all on how you wheel and what type of setup you want.

I didnt want something that wore balljoints left and right. I also wanted to run big tires on a DD.
O ya I know its strong.

I thi0nk it would be cool to have a IRS and IFS with alot of ground clearance. I think it would do well.

Cost for Cost I think SA is the way to go.

But if I was bill gates I would have one awesome IRS/IFS truck

To make your IFS big AND flex, you'd have massive IFS components. The solid axle drops down and then articulates, while the IFS has to both "drop down and articulate" at the same time.


And I don't think you must understand articulation differences between a solid axle fully.


But this'll help

I understand how it works.

Look at how low the front diff is in that vid. If you had a IFS that big ole front diff wouldnt be there. It would be higher and in turn give you more clearance and keep the front shaft high off the ground.

Also look at the passenger side wheel. See how it angles? That wouldnt happen with a IFS.

But yes in order to get it to do as well as a SA you would need massive components.

Just wait I but someday there will be a IFS and IRS set up for off roading.

While independent front suspension generally provides a smoother ride, it has a variable ground clearance to the front diff. As the front wheels hit a bump, the wheels rise up to absorb the bump. However the diff remains in the same relative position, effectively reducing the ground clearance under the diff. This can result in the diff hitting the ground, even though the obstacle under the diff was only half the height of the static ground clearance.

Live axle front suspension generally does not provide as smooth a ride as independent front suspension. However many live axle suspensions are now fitted with coils rather than leaf suspension, which significantly improves ride comfort. The advantage of live axles when off road is that when the wheels hit a bump, the whole axle rises with the wheels to absorb the bump. This maintains the same clearance from the diff to the ground.

So its saying when you hit a bump the diff can hit on IRS/IFS. And a SA wont.

I never said anything about jumping lol.

It's not about jumping. I offroad all the time and hit bumps. I don't fly in the air. When a solid axle hits that bump it goes up and over. When an IFS hits that bump, the wheels go up while the body(aka basically that center plate that's between the A arms) doesn't rise as quickly. Nothing to do with jumping.


Once again, there is a reason EVERYONE except desert racers chooses solid axle. There's really no argument about it, IFS has huge disadvantages over solid axle, when it comes to offroading.

When racing comes into the mix though, that's a different matter.

After reading alot I see why the solid axle is better overall. It also raises the body up when it articulates. It just seems the diff gets caught alot when I watch it out tv and stuff.

I have been looking for a good article but all of them are comparing stock vehicles to sas. I want something someone made lol.

this is incorrect. There are plenty of high dollar IFS systems that would kill a SA, its just the fact that they are high dollar that most people wouldnt want them. Alot of those big 10 ton and larger Army Vehicles use IFS.

Now im not arguing that IFS is better for wheeling cause it isnt, its just that IFS can be just as strong if not stronger then a SA. Alot of 600hp+ dune buggies run IFS style rear ends.

doubt it


an H1 will go more places than most of the Rangers on this site.. not ALL but most, sure its not a rock crawler, and i weighs in at over 9k.. but im sure it could take most Rangers here

Not really, just in some situations. Also, check on youtube for jeep vs. hummer. You'll see they're prettty easily trounced.

that's like saying a spaceship would kill my ford ranger in a race. It's pointless, with money anything is possible. With the same amount of money your highdollar trouncing IFs cost, I could build a better solid axle for much cheaper.

But once again, their purposes are different.

yea, by a jeep.. i know its no comparison..

but they are low and wide which really helps.. they are by NO means GREAT at offroading, but for a 4 wheel IS truck, it does pretty good..

BUT for $100,000+ you can build a wicked rig

Well I am not going to try to say IRS or IFS is better for slow off roading.

but what I have noticed is that the smaller rock climbers. Like 2 seat buggies that weight maybe 1500 pounds all have IFS and most also have IRS. Once you hit the jeep size they all have SA. So maybe its something to do with weight? Or maybe just the size of things you can start climing with a bigger truck? I do not know.

I was thinking you can put a sway bar on a atv or smaller buggy and help keep the other tire on the ground, but maybe with teh bigger vehicle there is too much weight and would snap one.

Just a thought. Maybe someday they will make some Badass IRS and IFS vehicles.

i havnt seen any purpose built rock buggies that are IFS/IRS... got picS? lol sorry..


i mean, im not against you, a really well built IS truck would be great.. but i still dont see an IS truck ever articulating nearly as well as a SA truck...
