I'm not SFA yet, but I will be by the end of the Winter.

Re: How many SFA guys are runnin around here?

I'm really new to this 4x4'ing world. What is SFA? What is the difference between SFA and IFS? Don't mean to sound stupid, just a little ignorant of this terminology.

Don't worry, everyone lacks knowledge about something, and gains it later on!

SFA = Solid Front Axle.
One solid axle suspended by front leaf springs or other kooky suspension setups. When the axle moves one side is directly affected by the other.

IFS = Independent Front Suspension.
Very short solid front axle, but with two smaller axle shafts at the end that move up and down to articulate. The shafts are held and helped with control arms on the upper and lower side of each wheel in the front. The suspension is generally torsion bar but could be coil sprung or ???. Each side is indpendent of the other.

Thanks, now I know. Does SFA provide better stability when off-roading? Why would you want to change your setup if you have IFS to SFA and vice versa? Is this a real pricey conversion if you decide to go that way?

Let me know, thanks.

Re: How many SFA guys are runnin around here?

Honestly it all depends on the type of terrain you're running.

I like running the desert at good speeds, so I prefer the IFS setup. It is one of those things that people argue over for hours on end!

In my opinion (that's my disclaimer). If you're running trails at slower speeds and need massive articulation, go SFA. If you're running hard and fast and need to have the right wheel independent from the left to compensate for terrain changes, go with better IFS.

Unfortunately there are no real good long travel IFS kits out there. I know of one guy who did a kit and works with California Super Trucks. From what I was told he got like 11" of wheel travel with 4 wheel drive but kept exploding front differentials. The extra wheel travel is one reason why folks go for solid front axle.

Either way you look at it, it's going to be pricey.

SFA is a custom deal. Install at your own risk.
IFS has some "kit's" available that don't really provide any real-world travel.

JR has it right. I'm going SFA because there really isn't much for desert terrain, and the only real good beach running happens in very early spring at the reservoir about 2 hours from my place. I don't get out much except for on long weekends, and depending on the snow pack in the mountains, i may only get to hit that beach on the May Long weekend (I'm in Canada, and it's the 3rd weekend of may.) The nearest desertlike conditions are about five or six hours from me, and that's just too much driving for a day trip, or a weekend. Everything else I do except for the fire roads up to the trailhead scream SFA, so yeah, I bought an axle (It's a Dana 30, it'll get me through next summer, then I can save up for a set of Dana 44s.)
Wise man once told me, learn to 'wheel with what you have. If you constantly find yourself getting stuck or breaking stuff, then upgrade. No shame in running IFS for a few years, or for ever.
