Looks good. Id agree that the bar between is beneficial - Id think itd work to strengthen the whole setup by essentially acting as a crossmember. Plus, if your pulling from just one of those shackles, i think it'd help to distribute the load.
Do you have it bolted through the holes for the factory tow hooks? Or where exactly did you bolt it to the unibody? - its hard to picture without looking underneath.
I know everybody here is critical of the strength of recovery point mounting. You definitely make a good point with the friction, that the bolts would be squeezing so hard that it shouldn't matter. I believe that the thin sheetmetal of the unibody is the main concern, as opposed to the shear strength of the bolts. Either way, i still think it'd be damn near impossible to rip that thing off.
Post more pics if you do any more fab work.
I think the cross-member is of great help.
its mounted through the factory holes although i drilled out the square holes to give me additional mounting points.
I plan on fabbing up some stuff in the near future. Ill definitely be posting it up.
I doubt you'll rip the mount from the frame rail. I'd bet good money you'll deform the crap out of it with a good tug or two with the single mounting plane like that though.
Your jeep, good luck.
I understand the concern of the lower sheet metal, but its all about proper loading. How much money you looking to bet? I used these on Saturday got a few tugs in the snow after i slid into a ditch.
I think that large point that is being missed here is the plate has 21 sq inches of contact with the frame. This distributes the load very well. I calcd out the stress on the 1/16" steel making up the bottom.
At the bottom is the shear stress exhibited on the steel in psi. Ill let you look up the yield strength of mild steel. If you dont reach the yield point there wont be any deformation. I calculated it with a force of 10,000 lbs on one side so i think its sufficient.
