I have decided to add some bell tech drop shackles to my 2004 f150 4x4 supercrew 4x4. I was wondering if anyone has these? Is it necessary to use the shims with a 1 piece drive shaft? Will it affect the mounting brakets for my borla exhaust? Is an alignment necessary? I have done a search, but none of the postings have answered my specific questions. Pictures would be great any any other info would be appreciated.

Thanks

 

You might try a search on the subject, but I think on the 4X4, to drop 2 inches, all you need to do is get 4X2 U-bolts and remove the 2 inch blocks.

 

Yea I have seen some people say that. I am just a little concerned if I do buy a set of drop shcakles I will be faced with a vibration issue? Maybe the block removal is the better alternative.

 

And cheaper. You may be able to trade with a 2wd guy who wants a little lift.

 

no alignment would be needed

and a 2" drop you shouldnt NEED shims but they wouldnt hurt, to get your driveshaft perfect, ive installed shackles on a couple trucks and didnt need shims, but if i were you id just remove the blocks

 

How much are the 2wd u bolts? Any part number?

Thanks,
Keith

 

How easy is it to remove the 4x4 blocks on a supercrew? I have heard pne person say the sway bar and drive shaft might have to be disconnected??

Thanks

 

that one person should not be listened too

 

to remove blocks
jack up truck HIGH
properly support the truck with jack stands under the frame not the axel
loosly place jack under axel just in case
Un bolt u bolts
pullout block
put on new shorter u bolts

 

and then drive off the stands right?


but seriously i would take the blocks out before i bought shackles.

 

That was what I thought when I read it!
