Using these rear lift shackles is straightforward. First, make sure your truck is parked on a flat and stable surface. You'll then need to remove the old shackles and install these new ones in their place. When towing or carrying heavy loads, these shackles will help keep your truck in a better position. As for maintenance, use the grease zerk to add grease regularly to keep the shackles working smoothly. Be aware that if you have a 2013 Dodge Ram 3500 with radius arms, don't use these shackles; instead, look at the parts for Dodge Ram 2014 and later models.
