Hi All -

I had both leaf springs break in my '06 dually. I purchased new spring packs from SD truck springs. They arrived, but they are without the rear overload (the big curved one on top that engages the brackets on the frame). I called them and they said they don't sell that one and that people either re-use the old one or buy new somewhere else.

Two questions ---
1) The spring pack they sold me has a center pin that wouldn't be long enough to bolt the overload spring on --- does this mean I need to dis-assemble and find a longer center pin?

2) I'm adding air bags to the set up at the same time, so is it even worth the hassle of getting this overload spring back on?

Any thoughts appreciated...

I had two F350 SRW with overload leaf and airbags. My current truck is a F350 DRW and it did not have the overload spring on it go figure. I put air bags on all three. I really don't see a need for the overload spring with the air bags. On a side note the first two trucks I lowered with F250 blocks on the axle the DRW I drop the springs straight onto the axle. That lowered my tailgate by 5 inches. The truck sits one inch high in the back now, a lot easier for loading and unloading. I use airbags to keep the truck level with load/5wheel so my lights are always adjusted correctly.

If you look at your aux spring and how it mounts, you'll see there's a small intermediate block between the main spring pack and the aux spring. That block has a hole for the head of the centering bolt on the main spring pack and a stud sticking up to engage the aux spring. The only thing you'd need is slightly longer u-bolts, that small block, aux spring leaves, and the frame pads that engage the ends of the aux springs to add them to a truck that came without them.
I have air bags on my truck and pump them up so the aux springs are about an inch or so clear of the aux springs with my camper on. Then when I hit a big bump, the aux springs engage to take up some of the load.

so I went to pull off the overload last night so I could take it to a shop and have a new one made. I started removing the nut at the top of the stud sticking through, and the stud eventually broke (nut was rusted on). It looks like the center pin goes up through the spring pack, through the block under the overload, and through the overload itself.

My new spring pack has a stud that stops at the top of the spring pack. Wondering if I could throw the overload block and spring on top of that and use the u-bolts to hold it down or do I need to replace the entire center pin?
