UMI Performance Leaf Spring Shackles

UMI Performance leaf spring shackle kits work with a variety of stock location leaf springs. These kits include bushings for both leaf and chassis side, Grade 8 hardware, and new laser-cut shackles. Polyurethane or Delrin provide a good ride quality with a performance improvement over stock rubber bushings; and the shackles are black powdercoated for improved looks and durability. UMI Performance leaf spring shackle kits are a great choice for street and performance use.
