2007 Toyota Tundra Replacing Shackles
The shackles that attach the leafs to the frame were removed, as well. Notice the OE and longer aftermarket shackles compared to each other. The new shackles were bolted onto the ends of the leaf springs. There were two sets of bolts on the parts of the shackles that attach to the frame, which give the option to go low or lower. We chose lower.
