Detroit Truetrac – Smooth Maintence-Free Traction

Eaton’s Detroit Truetrac was the first helical gear differential ever introduced into the automotive aftermarket, and remains the leading gear-type limited slip differential in the industry.


  • Smooth Operation
  • No Maintenance
  • Traction when you need it!

Detroit Truetrac’s proven design eliminates the need for wearable parts, resulting in maintenance free traction. Recognized not only for its durability but also it’s smooth and quiet operation. Engineered to work efficiently in front and rear axles, semi-floating (C-clip axles) and transfer cases. Power transfer is so smooth, it literally goes unnoticed by the driver – even in front wheel drive axles.

Proven design 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!
