Kit came with shackles, staked threaded shanks, nuts and bushings. Thread form is 7/16x20 (fine thread.) I ordered two kits. One came with 5/8" lock nuts, the other came with 11/16 non-locking nuts. Now my LH side won't match the RH side. I had to order lock nuts (pkg of 10, min qty) so that the two sides match. Weak quality control at manufacturer. Installation and performance is as expected.
