Some axle trusses I just built for the axles going under Stan's new buggy. The top plates are 3/8" and all the rest are 1/4". Every piece on these trusses keys into at least one other piece making these incredibly strong and bullet proof. He will never have to worry about bending an axle. These were all designed and cut here at Rock Solid Fabworks.

It didn't look like the truss was close at the punkin'.  Is the intention to NOT weld the truss to the punkin'?  Just curious.

Yes, this design does not need to be welded to the pumpkin. Also by leaving all that space open some the truss can be rotated exactly where it needs to be, especially on the rear. Trust me once these are welded in they ain't going any where.

I don't doubt that it's strong.  I was thinking of weight and height reduction without compromising on strength... I'm also thinking if you mounted links to the top part it would cause some other odd stresses. 

*shrug* they look plenty beefy to me.  I've seen several designs lately that didn't ahve the punkin welded.  Was curious why someone wants to do that. In your case I'm guessing you'd like to have the same pattern regardless of the alignment of the truss. That way you can generically sell a truss without caring for what alignment your customer wants...?

If you weld to the punkin you have to have a specific alignment and cope the steel to the surface of the punkin at that angle.  Any change in the angle would force a different profile of the truss.  For you that would mean a lot of manual work to attach it.  Is that the main motivation?

Tieing a truss like this to the pumpkin is pointless.  Look at the pics the top pieces tie into the risers via key way slots which get fully welded.  The risers are 2" apart on centers and then the gussets key to the risers then weld to the top plate.   These trusses will NOT BEND or FAIL,   Money back guarantee if I weld it in!   The reason why they sit up off the top of the diff about 1.5" is to get proper link mount seperation, so you can run the lower links at the center line of the axle tube so that nothing hangs below the axle tube to hang up.   Trust me we didn't just throw something together.  These were designed and cut to take years of abuse and once again if I weld them in at my shop I'll guarantee them for life.
