I would like to add helper springs to my truck currently the spring pack is 2-1/2 inches wide. The helper spring pack that I have is 3 inches wide, if I get longer U bolts can I use those helper springs or am I better off getting helper springs that are 2-1/2" wide? I am putting this on my ' 64 F350 4x4 dually.

 

i think you would be better off geting 2 1/2" helpers because of your springs being a 1/2" smaller causing slop possiably. i'd recommend to get the airbag helpers. they dont change the quality of the ride at all

 

that is a very good idea, I never thought of getting a airbag, thanks

 

I'm running 2 1/2" helper packs (5 leafs) on my 3" springs. Both springs and helpers were new when I put them on and they've been riding great. No slop, twist etc As long as the U bolts are tight, and the top plate isn't worn you should be alright

 

My setup will be the opposite from your, do you still think it will work?

 

Not what you are looking for but I helped a guy move his trailer (14x70 with tip out). He placed 8x8's as "Spring Helpers". Amazing but the truck moved it. Of course the tip out left a few scars in the road. Funny what people will do to save a professional moving bill.

 

It probably won't work because your top plate is only 2 1/2" wide, so it won't clear the overloads. Even if you went with a wider plate do you have room on the axle to space out the u bolts to 3"? I'd be a little leary of the bolts shifting a bit being wide on biggest part of the span

 

I do have the room on the axle, but I have the same feeling that you have with the U bolts shifting. Thanks for your help.

 

Try the coil helpers from advance. The heavy duty kit is $24.95. The coils u-bolt to the top of the axle and the frame rupper stop rests in the center of the coil. They worked for our Suburban (echh) and f100
