Perhaps that was poorly phrased - what I'm actually referring to is the tendency of an IFS vehicle to lift the entire front end when one wheel is forced upwards, for example by a rock, or if the track rises on one side of the vehicle, but not the other - solid axle "purists" claim they get better traction, because of better articulation, when the wheel on one end of an axle is forced upwards, the opposite wheel is forced downwards.

I understand that what you're telling us is how you've experienced it, and I'm not disagreeing with you - it's just that I find your story interesting, given the claims made by the purists - I have not been behind the wheel of a solid front axled vehicle in about thirty years.

If you have a manual transmission, throw a Lock Right into your rear axle.  The rear axle will provide you more traction, particularly when climbing hills when the weight transfer to the rear of the truck. 

My Tracker has had a Lock Right in the rear axle for about five years now.  I drive FAR more frequently on the open hard ball road than on trails and I have never regretted installing it.  I rebuilt my rear axle and diff about a year ago and re-installed the same Lock Right with a rebuild kit and new cross pins, and honestly, it operates so smoothly I rarely even notice it is back there anymore.  It only rarely pops and the only other sound I ever hear is the ratcheting when coasting through turns.  I have to have my window down to hear it though.  With the front hubs locked, it has predictable manners even on snow covered roads.
