Front springs I’m doing a RUF pack that’s a mix of fronts/rears and one leaf out of an old Marlin 4” rear pack. I’m not going for a flex monster. Just looking for low height and more articulation than I had with IFS.

For rear springs I have a pack of 57” Allpro rears off a truck I parted out. I’ll mix and match some leaves into it to make it work. If I can keep the front low enough I might be able to get by with my current OME rear springs for a bit.

Steering I’m going to push the IFS box all the way forward and up, rotate the box so it’s “flat”, flat pitman, then notch the frame for the drag link nut. I want the pitman arm swinging juuuusst under the frame rail.

This should give me as low as possible without crazy amounts of fab. Shooting for a frame height of <23” with 35s.

Got some RUF packs made. I used the first three leaves of the rear pack and added two leaves from an Allpro lift spring. I may need to add a sixth leaf - these are pretty soft.

Looks like my shackle will touch the frame just before the pack goes flat. I might scoot the front spring hanger forward a smidge, but I’m liking what I see, so far.

Im at 45 3/8" pin to pin up front.

I’m definitely too short then. I read somewhere that you measure your spring length, subtract shackle length, and add a half inch to get hole placement. Spring measurement gave me 47” along the arch, but I’m reading that it’s actually 48” so I need to scoot my hanger another inch forward. Easy enough. It needed to come back off anyway.

Scooted the front hanger forward a bit. Put weight on the springs and rolled a tire under. It moved forward quite a bit with the RUF springs. It’s mocked up at about ride height. I’m hoping these springs settle about an inch. Frame heigh with the ass end hanging down is 24” at the Tcase crossmember.

Anyone have a good source for JUST Ubolts? Are 5/8" really necessary? or is that Pirate4x4 talking? Everyone sells Ubolt flip kits. I have the plates already from a part-out rig, but maybe buying an entire kit is the way to go.

I didn't realize you had a build thread for this. You already know how much I love this thing. I'm bringing a case of beer over just to watch you work.

Got my sliders btw, It will take me longer to paint them and install than it will take you to finish a SAS

5/8 not necessary. Diamond uses 9/16.
Have you looked at summit, etc?

Negative. This is going to take a while.

You can drink beer and watch me. Here's what you'll see: I'll stare at my truck, lose my measuring tape, forget what I was thinking, go back to staring, place a tack weld, lose my marker, go inside for coffee, get distracted, come back out, remember I was looking for my marker and measuring tape, give up, go back inside.

Ok. 9/16 it is. actually found a good selection of Ubolts on SDtrucksprings.com, but shipping is a bitch. Still looking.

I usually go to local spring shop and they make U-bolts while I wait and how I want them. New tall nuts are included.
