Looking at maybe expanding and picking up a tractor for our outfit here in a year or so, and I'm pretty biased towards the Air Trac 4 bag suspension by Peterbilt, for working in the dirt everyone says that its one of the best air rides and I have to agree from experience. The problem is though there don't seem to be as many trucks like this that come up for sale, have to figure way more Air Leaf trucks were made to as for OTR vs dirt trucks.
I got to looking at the spring hangers though and they seem to have the same footprint, 6 bolt of the same pattern, which got me to wondering if a guy picked up a good Air Trac cutoff if it would be a pretty easy swap. Looked on the Peterbilt body builders manual, and everything looks like it may line up.
Anyone on here tried this before? I'm pretty familiar with the Air Trac setup, but am not at all with Air Leaf.
