Hittin' the links...

I will just give you a couple link options for your truck.

First off, there is the 2 link. This is dirt cheap and works, but a couple problems arise. The bars pivot on the frame but are welded or bolted solid to the axle. The problem with this is that when on tire goes up, the other wants to follow. The other problem is that the pinion angle changes drastically as the truck is raised. This could start breaking things. The pinion angle is the angular movement of the driveshaft. The sideways movement of the suspension can also make stress point that will fail over time. The 2 link is not a very good option if you don't want any problems.

Secondly, you have the 3 link option. These are much better than the 2 link because they have two parallel bars running underneath, and one or two on top running from the axle to the frame. The one with two on top is called a wishbone 3 link and connects to the frame at 2 locations, while it connects to the axle at on location or vise versa. Here is a picture of a wishbone 3 link.

Just make sure everything is strong because a lot of the strain will run through the top link. The linking bars are connected on the axles with a hinge instead of being solid. This makes suspension movement much easier and flexible than the 2 links system. The only problem with a 3 link is that you need to install points to attach the bars. A 3 link is a great choice as long as it is made properly.

Thirdly, you have the 4 link option. This is basically the same as the 3 link, but you have two upper bars instead of one. This greatly reduces stress on the whole system. A 4 link will also reduce pinion angle change. The way I look at it is that, if they were to install air suspension from the factory then this is probably the system they would use because is keeps the vehicles suspension in balance.
