Eaton | TrueTrac | 9 inch Ford | 28 Spline | 912A587

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. Operation of the Truetrac is smooth, quiet and automatic. The unit will engage without any driver knowledge or action required. It also has no wearable parts and requires no maintenance, meaning less time in the garage and more on the road.
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.
