Update: I originally said I would be holding off the SAS for a few years or so and just do a conversion instead. After talking around, I've learned a few things about ifs. For one, putting an air locker on an ifs is apparently just begging to snap an axle every time you flip that switch. So, after looking into an SAS a little more, I have a few questions is like to run by some of the more experienced mechanical people currently subscribed to this thread.
(And I do realize this is an Xterra thread and I'm running a taco, but the underside components of a 4wd aren't apples and oranges on different vehicles. Kind of.)
1. Aside from the transmission, transfer case, and front drive shaft, what parts (if any) will I need from an ifs to do an SAS?
2. What are pros and cons between a leaf spring setup vs a coil over? Which is easier to build, setup, service? Which gives better handling on vs off road? I've looked a fair bit, and I don't see any how to's, most are just "then after I cut all the ifs off, I put the axle underneath and rolled some tires next to it to see how it looks. Then after I finished putting on the axle,..."
Thanks in advance for the help!
