    your front axle moves back when the springs compress, don't worry if you have splines showing, just make sure it doesn't bottom out under full compression or you'll shove the driveshaft into the transfercase and break fun stuff like tranny to transfer adapters and such.

    The front shaft I've got has just over one inch of travel. Not much to me.

    You need to make sure the front axle isn't "hanging off" of the driveshaft at full droop. Probably unlikely that you will run into that position, but I'd be most comfortable knowing that I wasn't going to overcompress it in stuff AND overextend it.

    yeah, safer to have the shaft come out then have it jam everything up

    Yeah, it's a great way to break an aluminum xfer case.

    a stock shaft has about 3.5 inches of travel. unhook it from the yoke and see where you are in the travel. if you can't pull the shaft out any further then you should probably lengthen it. if when you unhook it it does not droop any further then the yoke then you are maxed for angle. also another case where you will need to change something. you can grind the stops out of your CV to get more angle but it will shorten the life of the joints.

    No, that's the amount of travel that my stock front driveshaft has! Not a lot to play with.

    Every stock front driveshaft I've had an opportunity to measure has at least 3" of travel. I'd say I've checked at least half-a-dozen.

    Is your shaft somehow from a newer IFS truck. I believe they don't have much travel because, well because it's an IFS and the diff isn't moving.
