So I'm doing a f250 spring swap on my 94 f150. I'm looking to buy Dayton 5 leaf, leaf springs from rock auto. Now my question is what size u bolts do I need to make this happen? Rock auto has a few different sizes. I'm looking at ones that are 5/8" x 3 5/8" x 10 1/2". Will these work or do I need longer u bolts? Thanks for any input. Ben

 

Also, should I be buying 4 leaf, leaf springs? Or is 5 what people normally do for this swap?

 

Contact ATS Jr. thru this site. He can answer any questions and hook you up with a better product at a better price.

 

thanks for the reply. and ATS Springs is a reputable company? I came across them before but I didn't know how reliable they were and couldn't find many people who had experience with them.

 

Hey Ben! If you want send me a message. We make all our Ubolts from straight rods so once we determine which size you need I can make them right away for you.

Also we can take a look at what springs would benefit you the most!

Plan on replacing shackles too, F150 springs are 2.5" wide on these trucks, F250+ are 3". Just a heads up.

 

Not all of them, My 90 F150 has the same 3" springs as my 89 F250, all factory stuff. The 90 has 4/1 leaf with an overload on top and the 89 has 5/1 with an overload on top, all 3" wide.

 

F150 2wd have 2.5" wide leaf springs. 4x4 has 3" leafs, and I have a 4x4 so i won't have to worry about that.

 

Dang it! I keep forgetting that there are 2WD trucks out there!
BTY, some cab and chassis trucks have 2.5" springs, also. That's where my D60 front came from and that's why I still have the TTB springs. But ATS has quoted me new stuff and I've almost got the money saved up to get them. I sure am looking forward to that smoother ride!

 

Wish I could say the same but I don't even know what mine drives like. I got it last summer and still fixing it up. Never driven it on the road. I just want the lift kit and 35's out so when I do drive it I dont get 8mpg
