These Eaton Detroit Truetrac differentials use a patented design of parallel-axis planetary helix gears to provide a quiet, automatic splitting of torque. They perform like an open differential under normal driving conditions, automatically transferring torque to the wheel with better traction when ground conditions warrant
The Detroit Truetrac was the first helical gear differential ever introduced into the automotive aftermarket as an Eaton brand. It remains the leading helical gear-type limited slip differential in the industry. Detroit Truetracs proven helical gear design eliminates the need for wearable parts, resulting in maintenance free traction recognized not only for its toughness, but its smooth and quiet operation as well. Proven design, low cost and effective performance all make the Detroit Truetrac limited slip differential the ideal choice for a wide variety of vehicle applications. No maintenance - Just Traction.
Most LSD manufacturers insist that their customers use only costly high-grade premium LSD oil as well as expensive LSD additives to not only maintain the longevity of their products, but to also warrant them. Eaton took these expensive additional running costs into mind when designing their range of Truetracs, and through rigorous testing have manufactured their LSDs to happily suit any generic diff oil. This makes the running and servicing costs of a Truetrac far less when compared to any OEM LSD, KAAZ LSD or virtually any other clutch/cone type LSD. Just another reason Eaton remains such a popular LSD brand worldwide.
