For the steering and track bar connection, you can go two routes: You can choose to leave the steering and factory track bar in their stock locations, or you can add Pure's track bar bracket and the flip spacer into the pitman arm.
The flip spacer is designed to flip the draglink from the top of the pitman arm to the bottom. Pure does this to take full advantage of the suspension droop without any fear of binding the steering. You simply drill out your pitman arm and insert this spacer before bolting the draglink back on (to the bottom this time).
When you lower the draglink mounting point, you need to drop your track bar to keep parallel geometry and minimize bumpsteer. The track bar drop bracket accomplishes this and allows the suspension to use its 12 inches of travel.
