Many owners of the 98-02 Firebird/Trans Am/Camaros are always looking for all the possible upgrades for their vehicles. Whether it is a bigger motor, bigger brakes, louder exhaust or a TRAC LOC rear axle. In reference to the TRAC LOC rear axle, many owners don’t know the difference, or what the advantage is to a TRAC LOC axle.
The difference in the axle isn’t something that can typically be seen, since the biggest difference is in the gear box. Here is a complete diagram of a true TRAC LOC axle:
One of the main purposes for this type of axle is the TRAC LOC will allow both wheels to continue spinning simultaneously, instead of locking them up when sensed.
Another key component in a TRAC LOC axle is the throttle relaxer that sits under the hood (PICTURED BELOW). The trac loc feature will not work without this part.
To show the difference in the whole axle, here is a picture of an axle WITHOUT TRACTION CONTROL:
Now some pictures below of an axle, WITH traction control
As you can see, the axle with the trac control has more wiring for the feature.
From all the pictures above, you can see the main difference in the two main Firebird/Camaro rear axles. Neither one is better or worse than the other, it just all depends on the users preference.
