    i know someone with a 6" on a K5 and he did a transfercase drop to help the angles not sure how much of a drop he did though.

    I had an '86 K20 with 8" front and rear Skyjacker springs once. Did not have to drop the t-case either. Sold these springs to Blzr4x4ngkid and sold the truck to another party.

    I have 8" skyjacker springs on the front of my 79 K10 one ton. In the rear I have a shackle flip, add a leaf, and 4" blocks. My Tcase is not lowered. The angles are not ideal, but eventually I'll get a cv driveshaft for the rear and it will be all good. For now it works fine. I replace my ujoints about every year or so. Your angles will be better because of your longer driveshaft.

    The big problem with dropping the crossmember or not depends on what tranny/t-case combo you have.

    If you have the 465 tranny, the front driveshaft is gonna be the shortest of any tranny and will/can cause binding in the cv joint.

    If the 350 tranny is there, its a little longer than the 465 and the driveshaft is also slightly longer, too.

    But if you have the 400 turbo, its longer than the other tranny's, and if the truck has the 205 t-case, the shaft will be longer yet.

    Unless you hook up a 208 t-case, the shaft on the 400/208 are the longest and allow for the best clearance on the cv joints. Lowering the crossmember is not required for this setup.

    79Beast also has a high angle CV front driveshaft. With a conventional cv driveshaft and the 465 tranny, the angles are too much unless you lower the t-case, in which case it still might have too much angle.
