Review on 🔒 Detroit Locker 913A477 Trutrac Differential: The Best Fit for Ford 9.75" with 34 Spline by Johnathan Delic

freezes on hard acceleration in every corner. If you accelerate hard in a straight line, it shifts from left to right, throwing the front end in different directions. When shifting gears at high speeds, the left or right tire hums. In snow and rain he's like a locker, he doesn't drive without a 4x4. Not recommended for off-roading as it won't block when you need it. F150 owners should get out of their electronic lockers and use the Raptor module (mod) to lock up both tires at speeds up to 100mph. Bought mine from Summit Racing. This purchase turned out to be a waste of money.
