The most common question we receive is "how do I lift my Quadravan". We don't offer a lift at this time,
but some van owners have sent us pic's of some of the diff ways they have found to get the job done. The pic shown to the right is the most common way to gain some hght. (This one is a little taller
than we would recommend). An inch or two does not require modification to any of the other suspension components. The higher the suspension is lifted in this way, the more screwed up your
suspension and steering angles will become. When the suspension pushes the axle farther away from the frame, without lowering the rear radius arm brackets an equal amount, the pinion angle will rise
and the steering angles will change. The yokes that are welded to the ends of the diff housing are set to a specific degree before they are welded together. Most of the time, axle yokes are about 4-5
degrees negative. As the pinion lifts, the yokes become more positive. You must keep the alignment angles the same! As mentioned above, this can also be accomplished by lowering the rear radius arm
mounting bracket equal to the amount of lift. The next problem, when a Quadravan is lifted, you also need to lower the track bars center (engine cross member) mounting point. This will keep the bars
at the stock OEM angle. If the angles are increased, the suspension will ride harder than ever, as well as increasing the stress on the already overworked track bar system. |
