    913A586 is rated 4.6 out of 5 by 5.
    Rated 5 out of 5 by from Great Product I bought this Trutrac for my 1985 F150 4x4 that had a limited slip from factory but it started to get tired. Install is super easy compared with a ford 8.8. I also resused my 3.55 gears. What you see is what you get. You need marking compound and new bearings. Measure your backlash before removal of the stock carrier and check your old wear pattern. Overall I am very pleased. There is no noise and driving on ice and snow it doesnt behave different then a stock one would except more grip. In the future i plan on buying another trutrac when i do a solid axle swap for the front.

    Rated 5 out of 5 by from great price Truetracs are excellent, and the price on this one was hard to beat. It's going into my '69 Mustang as soon as the weather allows for some working time on the car.

    Rated 3 out of 5 by from Poor packaging, broken box Packaging was terrible. Jegs didn’t box the differential, just left it in the factory shipping carton. Box was broken through on three sides. Otherwise good price.
