Can i use 4" shackles only in the back ? is it really necessary to use the hangers as well ? i know the pinion angle will change but i dont think that much , can anybody confirm ?

 

I don't think there is such a thing as 4" drop shackles, those would put the leaf spring eye into the bed of the truck. 2" shackles are sometimes enough to cause a bad pinion angle and vibration. After my 2" shackles I needed 2* shims to help reduce some vibration.

 

Ferocity02 is right, they dont make a 4'' shackle. I've looked. You can either do hangers and shackles to get 4'' of rear drop, or flip the rear and try to bring it back up 2''.

 

okey i tought so, i just read somewhere that you can drop 4" by shackles only, but thats just wishing i suppose !

 

i see beltech sell 3" drop shackles ? if the make it it would be useful ?

 

You would be just about in your bed floor with those. Curious to see if they make them or not though.

 

shackles and hangers are the way to go. like others have said any shackle over 2" would be thru the bed

 

my 3" shackles got just clear of the bed, i got them from belltech, i can take a picture and post when i have installed them

 

take a pic of the actual shackle, 3 in. drop in the rear will put it lower than the front

 

i also have 2" drop spindles to the front
