Product Details

The Detroit Locker 912A317 is a Detroit Truetrac helical gear differential designed for GM 7.5/7.6 inch 10-bolt rear axles with 28 spline axles and 3.23 gear ratios and up. This innovative differential uses a patented design of parallel-axis planetary helix gears to provide quiet, automatic splitting of torque, performing like a limited-slip differential under normal driving conditions and automatically transferring torque to the wheel with better traction.

Key Features:

  • Helical gear aftermarket carrier style with no clutches to wear out
  • All gear-driven clutchless design that smoothly transfers power from the slipping wheel to the non-slipping wheel
  • 28 spline axle shaft compatibility
  • Compatible with 3.23 and higher gear ratios
  • Fits GM 7.5 and 7.6 inch 10-bolt rear differentials
  • No maintenance required - no friction modifiers needed

Eaton recommends petroleum/mineral based GL-5 80W90 gear oil for all Truetrac differentials and does not recommend synthetic gear oil or friction modifiers. This differential carrier provides reliable traction enhancement for street-driven vehicles, offering superior performance over open differentials without the harshness of a full locker.

GREAT PRICE AND WERE JUST WHAT I ORDERED.THANKS FROM A SATISFIED CUSTOMER.

Nice straight forward process

Happy with the purchase.

Great job fast

Best price and the shipping was not padded with invisible handling charges like you get with other vendors.

ordered 4 cans to prime/paint/clear coat some rims. paint came in 2-3 days (incredibly fast). They forgot a can, i emailed and got a reply within 20 minutes, and the can was on my doorstep the next day. im very impressed

Fantastic service and fast shipping! Lowest price on the net for the CAI that I bought!<br><br>This is my new "Go To" website for parts.<br><br>Thanks!

I would def order again from them great price and fast shipping.

Wow the quick service and low prices at autoplicity helped me and made it easy to find which car parts retailer is the best!

Great price and fast shipping. Can't wait to try these pads out!

Good selection, lowest price. Fast shipping. Thanks again!!!

Autoplicity had the best price on the Wiseco pistons I needed anywhere. Took a little longer to arrive than I expected but apparently that was due to the pistons being shipped directly from the factory. Otherwise a very good experience overall.
