I just installed a set of 5100's on a new to me 2006 6.0 Super Duty. Did you torque the top nuts on the front shocks to spec and if yes, how did you accomplish the task? I sure couldn't figure out how to do that with my standard torque wrench. For the next install, this looks to be the ticket and I would have ordered one had I known I would be wanting it. Strut Nut Socket.In case someone does not know, there is no way to use a wrench to hold the top of the front shock, but there is a hole for an Allen Wrench in the top.
I got pretty close by estimating the torque, but I do like to get stuff precise.
