Description

What is the difference between a Truetrac and a locking differential?
Truetrac differentials utilize helical gears for smooth, automatic limited-slip action, unlike locking differentials which engage mechanically for full lock.

How does a Truetrac differential improve performance?
Truetrac differentials achieve instant power transfer for aggressive acceleration and confident cornering, enhancing overall vehicle control and grip.

Eaton Truetrac differentials, designed as drop-in replacements, deliver a remarkable 9/10 for Street Performance and Track/Autocross usage. This helical-gear style limited-slip differential provides maintenance-free, smooth automatic operation. Install with confidence for superior traction and predictable handling on any surface.

What Owners Say

Owners and enthusiasts consistently praise the Eaton Detroit Truetrac for delivering smooth, predictable performance that eliminates the jarring engagement and squealing tires common with traditional lockers. The helical gear design earns recognition for being silent and maintenance-free, with many noting it's ideal for daily driving, towing, and mixed-use applications where passenger comfort matters. While users acknowledge it doesn't match the outright traction of selectable or lunchbox lockers in extreme conditions, the Truetrac strikes a balance that makes it significantly better than open differentials without the on-road compromises. The consensus points to exceptional build quality and seamless operation that's earned it a strong reputation among truck and off-road communities.
