I called
Wulf Suspensions early this morning to verify my install and I have the shackles installed correctly but not as seen in my photos above. The H-beam should be facing the front of the truck and the open side facing the rear of the truck. I left them a message and I received a call back in under 15min. That's crazy! :)
I also made some recommendations on how to make this bracket even cleaner for the 2nd gen trucks (fits 1st and 2nd gen) and they were very responsive and asked me to send them the info. The customer service and component quality is pretty awesome so I'm glad I stumbled upon them on Amazon. The shackles would be a good fit for someone wanting 2" or 3" of lift but doesn't want the added expense of lift blocks and AALs. For $53 and something you can easily install yourself it's a win.
