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 Truetrac's 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. The TrueTrac requires NO maintenance (no clutches to wear out) and no need to run a limited slip additive in the rear end lube. True Tracs have a one year warranty against manufactured defects.
