    Got into a "discussion" today about 4x4's and the topic somehow came to solid axle vs. IFS. I know that solid is the way to go, but i need some good info. to get my point across. His argument was that they use IFS on the baja trucks and they take a good pounding. Thank you all.

    uh-oh

    The IFS on baja trucks are custom made first of all. Second most of them aren't four wheel dirve. IFS from the factory is weaker, harder and more expesive to modifty/lift, has more u-joints or CV shafts, limits travel, has more bushings, just a whole bunch of extra crap. It was designed to give a better ride on the road. I'm sure more people will comment. Later - Doug

    Tell him that if all IFS trucks came from the factory with super long A arms with 17" of vertical travel, a tubular chassis and Bilstein shocks then maybe IFS might be better, but as long as they come with wimpy A arms and 2.13434343" of wheel travel a solid axle will always win.

    I thought I was wrong once,
    but I was mistaken

Then if he is still not convinced then you will just have to get out the tow strap and hook them bumper to bumper and show him :-)

    Well my truck is proof. Didn't you know that IFS stands for Inferior Front Suspension? I converted my '95 Z71 to a Solid Front Axle. I had a 6" IFS lift before and I had to replace parts every other day on it. The SFA is much simpler and stronger. There's less to go wrong. IMO the only way to lift an IFS truck is SFA.[​IMG] Most Baja trucks I see have Twin I Beam suspension or whatever you call it not IFS. Maybe you could call that IFS. I don't know. SFA all the way!!!

    another thing you might want to mention is not only the limited travel, but when the tire on one side goes up it puts pressure on the other side so you get a better grip.

    Just open up any magazine... how many IFS trucks do you actually see on the trails. By trails I don't mean flexing on a curb at the mall. I'd like to see one of those baja trucks climb Potato Salad Hill at Moab. IFS is cool for PreRunners and the street, solid axles are for the real trails. You can't compare the two. Just my $.02.

    Yes it is. IFS is independant front suspension.

    IFS SUCKS. I knew this before I bought my truck, so I didn't get an IFS truck. Now, I have to pull home all the IFS trucks that follow me because they snap CV joints.

    My usual explanation is: Axle U-joints are cheap. I've never broken one, but they're $9 at Autozone. CV joints are expensive. Nearly everyone that follows me with and IFS vehicle trys to show off and destroys them. They range from $200-$500 in price.

    BTW, IFS lacks suspnsion travel, simplicity, parts availablity, strength to take a beating or to use a bigger tire, etc. It takes a lot of knowledge to put it back together (i know I could learn but I won't until I have to put someone else's back together) and, in a less technical sense, WHAT PROVES YOU GOT 4WD MORE THAN AN AXLE HANGING FROM LEAF SPRINGS UNDER THE FRONT OF YOUR TRUCK STARING SOMEONE DOWN IN THEIR REARVIEW MIRROR?

    EDIT: Twin I-beam is IFS. Any time the wheels in front can move independantly, it's IFS, whether it has coils, torsion bars, i beams, control arms, whatever.

    Thank you everyone for the info. Had the extreme upper hand in the discussion today. "Yeah, but they ride better and they're on hummers." &lt;--best response
    Thanks again

    Hummers ramp like @#$#@. I think the last time I saw the RTI of a Hummer/HMMWV it was somewhere in the 350 zone. What's a decent K5 ramp that isn't built just for flex? 500+?
