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. No maintenance - Just Traction.
Moser has changed their website to reflect the Motul gear oil as their recommended fluid for all gear type LSD’s (this includes Truetrac’s). Gear type units require friction to work properly. Most aftermarket oils have additives that helps to alleviate heat, wear and prolong life. In doing so these additives minimize friction causing gear driven units to be less efficient and sometimes fail completely.
