I've got a torsion bar suspension on my F5 Marmon-Herrington and no shocks. I searched through the galleries for other big trucks with this type of suspension and didn't see any. Is this the normal suspension for these rigs?

 

All they can be are an aftermarket add on. The truck didn't come with rear shocks. The only ones with rear shocks were F-1 and F-2, and optional on F-3. It also is not shown as a factory approved after market product in the Hildy's Blue Book - Special Equipment For Ford Trucks. I just went page by page through my Hildy's and it shows no torsion bar systems at all, only extra overload spring sets. And last, it's not shown in the "R" series MH literature. All that said, that's sure a stout looking system. Stu

 

I don't think that those are torsion bars. To me, they look like trailing arms. I see a leaf spring, hanger and shackle in the first pic. That would be your suspension system. The trailing arms just keep the axle in alignment. I've never seem them with leaf springs before. They are usually used with coil springs.

 

Here's one more picture of the set up. When we rolled it off the trailer, the way it flexed really looked like a torsion bar setup. I'll take a closer look when I get home. I was also thinking torsion bar because this was an old oil exploration truck that would have to be stable on sidehills, etc with a half tank full of water. That would put a lot of off camber stress on the suspension.

 

It's a "Truxmore" component. I've sent an email to the current version of Truxmore Industries to see if they can I.D. it for me. I've posted more pictures in my gallery. It's an extremely well made and robust component whatever it is.

 

i vote trailing arms that doesnt look like torsion bars ... torsion bars are adjustabel they dont look adjustable

 

They are adjustable. The end of the cap in the last picture has a large slot for adjusting and there is also an adjusting slot on the other end that attaches to the spring perch. Hopefully Truxmore will clear it up for me.

 

well i should have mademy self a little more clear when i meant adjustable i meant there should be a key on the end so you turn the rod to lift the truck but that definetly not waht you have

 

I know this is really digging up an old post, but I have the same setup on my '52 MH F5. Any word from Truxmore at all about it?

 

Since the question first was raised I've added a copy of the R5-4/R6-4 manual to the library. There is no listing in the Parts Manual for the Truxmore system. Nothing in the suspension or special equipment sections. You might check with Chuck to see what he knows about it, unless he drops by here to comment. Stu

 

I have two F900s with the Truxmore setup so its not specific to Ford or
a Marmon setup. Seen on many IH trucks too.. Just another add on or
dealer item......

 

They are just another product from Truckstell. Basically a traction bar.

AFAIK, the only vehicles that came with rear torsion bars were 1955/56 Packard's, and these bars were 9' long.
