Of course, when it comes to traction, some type of slip-limiting device like the Chevrolet Posi-Traction or aftermarket Detroit Locker or Auburn units or similar units will do an excellent job of hooking up both tires. However, these are not mandatory to get both tires to pull and not spin the passenger side tire. | Of course, when it comes to traction, some type of slip-limiting device like the Chevrolet Posi-Traction or aftermarket Detroit Locker or Auburn units or similar units will do an excellent job of hooking up both tires.

| − | With a front-motor, rear-drive vehicle, the chassis twists diagonally upon application of power. The left front gets lighter and the right rear gets lighter. The right front and the left rear get heavier. This is why you will see the right rear tire spin while the left rear hooks up on a car with a "one-legger" or "open" type differential. The right rear is light and needs additional weight applied to it. This can be accomplished cheaply and easily by installing an air shock on the RIGHT REAR ONLY to replace the conventional shock absorber on that side. Experimenting with the air pressure in the shock will allow you to equalize the weight applied to both rear tires on acceleration and "hook up" both tires without going to the expense of installing a locking device in the differential. I've done this many times and have seen other racers do it with equal success. | + | With a front-motor, rear-drive vehicle, the chassis twists diagonally upon application of power.

An additional benefit is that the car will be easier to drive at the strip with an open differential that has been "weight equalized". |
Now, with the rear end nailed down and operating, it's time to move on to the middle of the car and take a look at the transmission and torque converter. | Now, with the rear end nailed down and operating, it's time to move on to the middle of the car and take a look at the transmission and torque converter. | ||
