The Detroit TrueTrac was the first helical gear (no clutches) differential ever introduced into the aftermarket as an Eaton brand. In short, the patented design of the parallel axis planetary helical gears provides a quiet, automatic splitting of torque. It performs like an open differential under normal driving conditions and automatically transfers torque to the wheel with better traction. This limited-slip system responds instantly to torque feedback, anytime, at any speed.
Geared For Go
Moser’s gears are available for nearly any application and are CAD, CNC machined, and computer-control heat-treated to ensure the highest-quality product. Moser even offers a ring gear lightening program (add $100 to any set of gears) for serious racers to save precious rotation weight. The process involves machining a smooth radius on the outside of the gear and can save anywhere from 0.5 to 2.5 pounds. In our case, we ordered a set of Moser’s street/strip gears with a 3.73:1 setup.
Getting the rearend back in the Nova was a snap. We made sure to fill the rearend with 3 quarts of Synthetic Royal Purple 75W90 gear oil (for limited-slip gears) and put some miles on the gears before any competition. While at this year’s Goodguys Del Mar event, we noticed the Nova’s characteristics and personality have completely changed since our install of the Moser components; it’s like driving a new car. Wasted power that used to be directed to one spinning tire is now equally split between two. This translates into faster times through the cones and makes more use of the available power. We can even have a little fun in the turns now by sliding out the back end with some extra throttle. Plus, burnouts have become a lot more interesting. CHP
