Low Range Off-Road leaf spring shackles are manufactured to replace factory shackles which are inadequate for off-road usage. These replacements are designed with many benefits over the OEM shackles. They're constructed from 1/4 in. CNC laser-cut steel, computer-controlled NC bending to ensure accuracy, with Grade 8 hardware for high strength, and special bi-color zinc plating for corrosion resistance. Low Range shackles are built to accommodate a full range of aftermarket leaf springs. Order the pair to complement your lift height application.
