Just one, in the yoke, for the kingpin...
There's pics over at OMA (with close ups) of a couple of us testing them.
Those are the geometry mules and some new patterns are being worked on as I find time. Right now they turn like no other.

The design was developed from frankensteined existing truck castings that had been extensively machined, altering their characteristics. Those who skate with me have tried them. The foundry patterns started as some alder left over from some wood projects, ripped down on a table saw, then band sawed, and some parts lathed, all sized to blueprints. Finished in polished lacquer. These parts were then taken to a foundry that makes gear housings for racecars among other things using A356 aluminum, heat treated to T6 specs.
The pivot geometry is steeper than an Indy. The aligned pivot may look like a tracker, but it's aligned with the kingpin bore, Indy's don't have this. This is why they don't turn deep and why they eat pivot bushings.
Notice the plates don't have 2 sets of holes. The whole casting fits within the modern plate bore. That old crap is gone, who the hell wants that stuff. The pivot bush is machined Delrin. The hangers are bored (straight) and are faced. The Axles are 6al4v Titainium at .313 dia. Not 5/16, not 8mm, the 608 bearings have a snug fit that won't jam. There is mucho clearance between the Titainium kingpin and the axle. Talk to Carlos about flying across the coping on those hangers.
The goal is to make a really light truck to compliment a bigger board(my test board is lighter than an 8" popsicle). And a truck that turns really well off setting longer wheelbases. And all around making available a truck that is right for F-ing 2009 (ALREADY), not one that was sitting in a proshop when I was a kid in 1979 (like these others that everybody seems to love).
Anyway, I am not a cranky old guy. I am just trying make something for all you skaters that deserve better.

and to clarify I looked it up and most titaniums are softer than steel, the real question I had.
