How much slip is good for a fixed yoke?

    On my rear driveshaft, I have about 2 inches or so for it to slip out and an inch and a half for it to slip in. I have a shakle flip in the rear, and I dont know how much the driveshaft would pull out if I was flexed. I would think it would slip out further than in. So do I need it lenghtened?

    All I have to say is that this is a quick geometry exercise. Assume that droop is limited by your shocks and stuff is limited by the bump stops. Then calculate the difference in driveshaft length.

    the pinion is in the center of the axle so there wont be that much slip needed during alot of compression/ extension compared to an offset axle (like the front).

    muddybuddy is right I have quite a bit of travel and still run the stock slip in the back, I think I only have like and inch showing and don't even use all of that, if you jump it and both sides compress you may need to do some figuring but I haven't ever purposly jumped mine. :rolleyes:
