Floyd,

Some of the wheelie is because of front springs and smooth moving front suspension components. All stockers and most super stockers retain the OE front suspension to employ a tall spring with stored energy.

In addition, in many cases, they use quality, double adjustable shocks.

The Caltracks that many stockers use perform much like a ladder bar and most of the SS cars have a four-link that allows some tuning of the wheelie.

You already know it is not magic, just attention to detail.
