Heavy-duty Shackle Kit — The standard attaching parts kit includes ¼” shackles, plastic bushings, and dry bolts. As the bushing wears, the bolt tends to grind against the shackle bracket. Over time, the bracket wears out, which can lead to a break. A heavy-duty shackle kit upgrade includes ½” brackets, bronze bushings, and greaseable bolts—each a significant step up from the standard. The benefit: added durability and peace of mind that you won’t be broken down due to worn bushings and brackets.
