    Detroit TrueTrac 913A561 Detroit Truetrac Differential Ford 8.8 in is rated 3.7 out of 5 by 3.
    Rated 5 out of 5 by from Pleased with new install Product came as expected with instructions. I installed this in a 2wd 2003 F-150 that is used as a daily commuter and spends 99% of its life on the road. I purchased this for the times I am pulling a trailer in the cow pasture or other times I need to go off road and need additional traction. So far it operates un-noticed on the road but I have noticed both tires grabbing when on gravel and pulling onto the highway. Only time will speak to the durability and longevity of the unit. I am skeptical about only having a 1 year warranty but I imagine most people that purchase this product are demanding a lot of it either on the racetrack or in a very harsh off road setting.

    Rated 5 out of 5 by from True trac limited slip This true track delivers power to the ground and still alowing the limited slip. There are NO clutches and lasting along time without service. The limited slip seams a lot tighter coming out of corners without the inside wheel spin. A must for a road race car.

    Rated 1 out of 5 by from Didn’t last 1 race Had this professionally installed in my 2005 ford mustang GT. Tested with it 2 days worked fine. Did 1 race at Willow springs and locked up before the end of day. What a pile. Waste of money.

    Does this carrier have a notch that will allow the installation of the stock tone ring?
