    how high does a ORD 4" shackle flip tilt the pinion ?
    will I need a cv or will a normal driveline be fine?
    I'm only doing a shackle flip
    just wondering if it points it at the case ?
    or if it the angle remains close to stock

    Should tip it up about 7 degrees, in a K5 that's usually about right for a CV. A typical block has about a 4 degree tilt to it.
    A k5 with a 4"+ lift will probably need a CV jointed 'shaft.

    the set up i run is: 4" shackle flip and 1" add-a-leafs on my 14bff with no shims and it works good, i think. i havent gotten it faster than 25mph but so far so good.

    I have ran the flip for years and it always works fine with a stock drive shaft. I first did it with the t case in the up position, then lowered it, both had no problems. Now i have a zero rate back there too and it works great. This is all on a 89 with a slip yoke 241.

    I installed a 4" ORD flip in my K5 and it sails down the road at 80mph with no problems at all. I'm happy with it.

    I did the shackle flip on my 91 Blazer and the vibration was so bad it made my teeth rattle. I put in a 6 degree shim to point the pinion back down and it got rid of alot of vibration but the yokes made contact in the rear and I still had vibration on take off and about 60 mph. I am going to drop the t case soon to see if it helps. I think I will do the SYE for my 241 eventually and get the kit and a new HD CV shaft from H.A.D. That should take care of the problems. I just don't have $700.00 right now.
