Since you have asked a legitimate question, you deserve a proper answer. Super Stock springs were designed and developed in 1967 specifically for the upcoming Hemi A body SS/B cars. Those cars were later redesignated as SS/A, and later still as the current SS/AH class. They were the handiwork of an extremely clever young Chrysler engineer named Bob Tarrozi, who was actually in charge of development for the entire program. These springs are "handed", as you are aware. The reason was, that Chryser wanted these cars to be extremely competitive "out of the box" so that if NHRA imposed the usual restrictions on the cars (which they always did) they could run without any additional, or non-original traction equipment. You see, the problem is that when you initiate a sudden release of torque to the rear wheels of your car, the resistance of inertia and friction tends to cause the entire rear axle assembly to try to rotate in the same direction that the driveshaft is turning. The result is that the driver's side tire is forced downward into the pavement, while the passenger side tire is lifted. That is why with a non-limited slip differential, only the passenger side tire spins. So what if you could load more weight on the passenger side tire when the vehicle was at rest ? If you could load an additional 50 -75 lbs on that passenger tire at rest, when the power was applied and the torque tried to "lift" the tire, it would be countered by the extra weight, you see ? That is exactly how SS springs work. The pass side spring is actually stiffer and has aprox 1.250" more arch than the driver's side. When the driver's side torsion bar is cranked up to level the car, it loads the pass side tire just as described. Some of us have dipped well into the 9 second range at the track with nothing more than properly installed and adjusted SS springs. They do tend to be a little harsh on the street for some tastes, although some of us have used them on a variety of street/strip vehicles for over 40 years without any ill effects. They do work extremely well, but like most automotive things, they are a compromise. To give you an idea of just how well they can work, I knew a guy years ago who was running low 11s with an open(non-limited slip) differential. SS springs and tire pressure allowed him to launch straight with no pass side tire spin at all. These springs will make your car sit higher in the rear. To get a lower ride height, many of us simply have had a spring shop de-camber the springs to our specs with no loss of efficiency whatsoever. Hope that answers your question sufficiently.
