The front hell creek springs slipped on like a dream. you can remove the front shackles for the install, but we were able install the springs with the shackles in place. We just had to pry on the bolts a little when they contacted the frame going into the springs. longer brake lines would be a good idea, but our truck had previously been modified by bending the hard line on the frame down. it'll do until the front axle swap happens. The shocks required a 237.8-inch eye-to-eye length at ride height and a max length of 28 inches eye-to-eye at full droop. We had a set of 27-inch-long shocks in the shed that worked out well.
