What Owners Say

Owners and enthusiasts consistently praise the Eaton Detroit Truetrac for delivering smooth, silent operation that eliminates the jarring engagement and tire squealing common with traditional lockers. Many highlight its predictable performance on-road, particularly when towing or navigating tight turns, with passengers no longer startled by sudden lockup. The helical gear design earns recognition for eliminating maintenance concerns thanks to its lack of wearable clutch packs. Users acknowledge it doesn't match the absolute traction of selectable or lunchbox lockers in extreme off-road situations, but most consider this trade-off worthwhile for daily drivability and trailer compatibility. The Truetrac has earned a strong reputation as the ideal middle ground between open differentials and aggressive lockers.
