Locking rear is standard on the 07 diesel, Front on mine is limited slip, I assumed it was standard since this truck was not a special order. But the truck also came without needing the front leveling kit, it has always been high in the front. It is marked SLT Heavy duty 2500 Has the 5.9 325hp 600ftlb torque cummins. It also has no rear stabilizer which i thought was a standard part.

The anti American Constitutional party (Democrat). Wants to dismantle your rights, limiting every aspect of your constitutional rights. Death by 1000 cuts is the tactic. Each cut bleeds constitutional rights to control you. Control is the goal.
