<strong>13. </strong>After finishing our font suspension we quickly moved onto the rear. The block kit comes with new U-bolts and as always, you never want to reuse U-bolts or double stack blocks. Since the rear end now sits further away from the frame, Trail Master supplies a relocation bracket for the rear brake lines. The installation of our rear Trail Master SSV shocks was pretty straightforward and easy. One thing’s for sure, these shocks are huge and allow for plenty of articulation of our rear suspension. Once we had our Super Duty back on the ground Mike went ahead and torqued the U-bolts to the recommended specifications. Anytime U-bolts are replaced, the truck needs to be sitting on the ground in order to properly torque the U-bolts.
