Please school me sir Dukie....

Double Shear: Definition: An advantageous, balanced shear relationship which eliminates bending, prying and tension loads on shear attachments while distributing an applied shear load over two shear planes in each attachment, usually in parallel.


I do not get it. I am not being a smart ***...but the knuckle is the only plane here making it single shear. If that bolt breaks, you lose your drag link AND your tie rod.

I am not understanding how it is double shear without the benefit of two parallel shear load points.


I only studied metals as they applied to nuclear applications...but felt I knew something.

the assembly eliminates all prying, tension, and bending loads on the bolt (transfer is pure shear). It also distributes the load though two points on the bolt instead on only one.

had nothing to do with the bolt. I was pointing out another benefit of the IROR setup, and it isn't an opinion; it's an observation.

Thank you....you make that part understandable...in a way.

I still prefer the WJ knuckle swap. The added benefit to me is going OTA with the track bar. Puts everything above the axle. By raising the draglink that high, it allows the smaller slope and angles necessary to do so.

I meant my opinion that doing the WJ knuckle swap is a better option. Hard to always convey everything in type.

One more question....does that mean the DS bolt through the heim is in single shear?

Ok...I will stick with reaming the WJ knuckles to accept 1 TON TRE's.

My opinion is that this will be a better option...for me.

I once had a track bar that had a single shear heim on the frame side mount...broke that frickin bolt 3 times before I fabbed a double shear bracket.
