The new Full-Traction lift shackles are easy to install. Notice the longer length. Once the old part was removed, ORU's technician simply set the new bracket in place using the upper shackle bolt to hold it to the frame side. Next, the axle was lowered slightly until the two corresponding holes lined up in each shackle. The lower main bolt (not shown) was installed sandwiching the spring eye between each side of the lift shackle.
