We ask what type of rear end you have when ordering a torque arm because the Strange Dana 60 (S60) rear end requires a rear mounting bracket that is shaped differently for proper fitment.
Our normal rear mounting bracket will work with any stock or aftermarket 12 bolt and Ford 9" rear ends. So if you order a torque arm and say you have a stock rear end and later down the road you get a 12 bolt or 9" rear end the torque arm will fit just fine.
The only time you would need to contact us for a different mounting bracket would be for the Strange Dana 60 rear. You can also modify your rear bracket yourself to fit the Dana 60 rear.
