This is a complete kit to go spring over on an FJ40, with or without a Shackle reversal. Welding is Required! The kit is comprised of 2 pair of Spring perches (front pumkin side is special), 2 pair of Spring hangers (with the extra reach to allow for WB extension), 2 pair of Ubolt plates, 4 pair of Shock brackets, 2 pair of Shackle hangers with bushings and sleeves (or 1 pair Shackle hangers & 1 pair of 2" x 1/4" wall DOM tubes), 8 - 5" Shackles, and 8 - 10" x 3.2" x 5/8" Ubolts with 4" of thread so they will fit whatever spring pack you use. The options are Castor corrected or Stock Castor Spring perches, Shackle Reversal with Frame tubes (-$25) or shackle hangers, adding the Frame Boxing Kit (+$150), and the Rear Disk Brackets (+$40). The total of the parts individually is subatantially higher than this kit and the Frame Boxing kit is discounted also. These come without Leaf Springs because there are so many differing opinions of which springs to use, if you choose to use a nonstandard width spring we can change things to best suit your springs.
