Product Details

The Detroit Locker 913A586 Truetrac is a helical gear-type limited slip differential designed for Ford 9-inch rear axles with 31-spline axle shafts and 3.25 and up gear ratios. This high-performance differential uses a patented design of parallel-axis planetary helix gears to provide automatic torque transfer to the wheel with better traction.

Key Features:

  • Helical gear design with no clutches or wearable parts for maintenance-free operation
  • Smooth, quiet automatic torque splitting under all driving conditions
  • Functions like an open differential during normal driving, automatically transferring power when traction is lost
  • Steel construction for exceptional durability and strength
  • 31-spline axle shaft compatibility with 1.32-inch spline diameter
  • Compatible with 9-inch ring gears and 10-bolt covers
  • Requires petroleum/mineral-based GL-5 80W90 gear oil (no synthetic or friction modifiers)
  • OEM cross-reference: D8OZ4216A

The Truetrac differential offers reliable traction enhancement for street, off-road, and performance applications without the noise, harshness, or maintenance requirements of traditional clutch-type limited slip differentials. Carrier bearings sold separately.

Fast and easy check out

Awesome pricing. Easy filtering to get the exact item.

Great first time customer

Very fast and easy item search and payment!

I had a great experience with Autoplicity. I recommend them for your auto parts replacements.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

pleased so far

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
