As you can see in this shot, the installed lift, which is placed in the perfect position for optimum lift leverage, fits perfect next to the Optima group 51-R battery. We would love to say we planned it that way, but this was actually just one of those lucky situations. Dakota Digital offers a simple equation to help find the optimum placement to mount the lift inside their instructions. Quite simply the instructions state: "With the trunk closed, the actuator (or lift) should be in its fully retracted position. When the trunk is open, the actuator should be in its fully extended position."
