I was looking under the bed of my truck yesterday and noticed this and have no idea what purpose it serves. It is located on top of the frame on the far back left hand side of it. Its about 12" long 4" wide and 1" thick. It bolts to the frame with two rubber isolaters so it pivots side to side quite a bit. It sits right between the frame and bed. I hope I described it good enough.




Sorry for the dirty pics but it rained yesterday and I didn't have time to wash it yet. Weekend project.

 

Spacer?

 

I have no idea. It does not bolt to the bed at all, just to the frame with those two rubber isolators. It can pivot side to side but it never touches the bed. Also it is only on the drivers side. Nothing on the passengers side.

 

It must be some kind of a vibration dampener.

Yep frame vibration damper. I was bewildered when I saw mine, thought it may be part of RSC, but then I came upon a thread in the 04-08 section.

My Fx4 has one two.

 

i heard they add 50 hp?

 

Your right it does, a smooooth 50 HP.

 

Are they only on the 4x4's? My 2wd XLT doesnt have one and neither does my dad's. We've also both got the 5.5' bed.

 

Flux capacitor

 

Not sure if it has to do with that (being non 4x4) or if wheel base is the deciding factor on who gets on.

 

Without a doubt, it is a dikfer.

 

Some ones bound to ask the age old question. Good one james lol. Ill just sit back and enjoy
