We can get Eaton's 8.8" differentials, though we will need to know the year of your truck so we can get the right spline count. Whether it will be a good upgrade or not, we're not entirely sure. There's arguments both for and against it. A lot of folks say that running an LSD up front can be beneficial to off-road handling. However, we've also heard that because traction control/AdvanceTrac brakes when slip is detected that they're of limited utility. Still, we have not tried a front LSD setup ourselves, so we can't speak from experience on the matter. Give us a call directly at 623-434-5277 if you have more questions or so we can get more specific about your truck.
