Product Details

The Detroit Locker 915A550 Truetrac is a helical-gear limited slip differential designed for Ford 10.25 inch and 10.5 inch rear axles with 35-spline applications. This advanced differential uses parallel-axis planetary helical gears to automatically transfer torque to the wheel with better traction, providing superior performance in challenging driving conditions.

Key Features:

  • Helical gear design for smooth, automatic operation in forward and reverse
  • 35-spline configuration for Ford full-floating axle applications
  • Maintenance-free design with no clutches to wear out
  • Iron construction for durability and strength
  • Quiet operation compared to traditional mechanical lockers
  • 12 cover bolts
  • Works with 1.50 inch axle shaft diameter

Lubrication Requirements:

Eaton recommends petroleum or mineral-based GL-5 80W90 gear oil for all Truetrac differentials. Do not use synthetic gear oil or friction modifiers with this unit.

The Truetrac performs like a standard limited-slip differential during normal driving, then automatically transfers power to the non-slipping wheel when traction is compromised. This provides excellent performance for street trucks, off-road applications, and towing without the harshness or noise of a full locker.

Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.<br><br>Best prices around.

Cheapest priced ARP head studs on the internet. A++ I will definitely do more business with Autoplicity.

Super easy to browse web site and find the product I wanted.<br>The price was unmatched.<br>Shipping was fast and cheap.<br>Super shopping experience.

Easy straightforward site setup.

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.

Excellent service with the actual stock on hand, shipment was made the next day and a tracking number was provided. I have tried 2 other online supply stores which don't know what they have in stock.
