Does anyone know how much longer the superduty v-codes are than the stockers. I finally started my kingpin D60 swap into my 89 F250. I have the sky manufacturing shackle reversal and can't seem to remember for the life of me, how much I need to add to their 52" measurement. I have all my D50 TTB out and tomorrow I plan to get the axle hung. I have been searching for 4 hours now and can't find that magical number. Any help would be great. Thanks
No, the truck is just an average 89 f250 4x4. What I'm doing is swapping the front springs to the 99-04 superduty V-codes along with a shackle reversal. They are longer than my OBS springs, but by how much I don't know. Unmounted they are 2" longer but that number will get bigger once installed.
Is that going to put the shackle at a 90* angle. Every picture I saw of this swap had what looked to be a vertical shackle. Shouldn't it angled to the rear or is the superduty spring an exception.
Do you mean heavy duty? I have not ever heard of a pre 99 super duty?
He's probably talking about the F-Superduty, also known as F59 stripped chassis - looks like a 1-ton only bigger, has a solid I-beam front axle with leafs and kingpins like a big truck, Dana 80 rear with massive disc brakes, driveline parking brake, 10-lug 16" dually wheels... Pretty nice setup really, can take lots of abuse as a work truck in its factory form or can be very nicely converter to full air ride for highway-hauler purposes, too bad at 14k GVWR they can get rather expensive to register and insure.
