Quite simply by increasing the surface area contact load from about 2.5 square inches top and bottom using factory washers to about 6 square inches top and bottom using plates. More surface contact with the same torque load.

The question is... did they fix it more than simply tightening the standard fasteners?
The standard fasteners loosened several times in the past. There was considerable movement in the C-beam with the bolts not quite factory tight.
With the plates, no more lossening over time, thus no c-beam movement, thus no unloading of the driveline, leading to more consistent (and quicker) ETs.

This is exactly my point. Performance gains are not found in the plates.
Yet better fastening strength is gained providing consistency.
I ran a GP on these and we had 30 or so guys buy them, but not for $180. The workmanship is outstanding and it makes installing the C-beam much easier. For just that, it's worth it.
^^Look at the workmanship there!! And somehow Strick did it for less than $180!
I still question the performance enhancing value, as no one has been able to clearly explain the benefit. Those that try only explain how lack of proper maintenance caused some sort of felling and these plates stopped the fasteners from loosening up .....but I'll never fault one for getting them....and anyone that has wrestled the C-Beam even on time would agree with me.

Maybe you missed the part about those being the same beam plates in question, from ZFDoc, but the GP brought them down to a cheaper price. Strick didn't manufacture those.
I wouldnt argue with anyone about those being a very nice looking, quality peice of work. But for me, first off I never had a problem with the beam flexing, at least that I know of. So in my mind the only real advantage would be ease of beam installation. That being said it wasnt worth it to pay $100+ for them. But making them like rodj did, I believe I will!! Besides, who cares what they look like? who's going to see them after they are installed?
I guess im lucky. Ive never had a c beam bolt come loose, And I dont think its very hard to take them out. An open end wrence on top nut and air gun on bottom bolt and they come out quite easily.

I agree, except I have pinched my fingers a few times trying to hold the wrench on top! And trying to fit such a big wrench up in there.
I installed them while I had my car apart earlier this summer - they seemed to reduce the tendency of the rear end to kick out on acceleration. They're probably not all that hard to make, but I got no skilz in that department.

Yep! You da Man Strick!
And like you said "makes installing the C-Beam much easier". For me its a matter of ease when checking the torque each winter.
One question, how tight is too tight on these bolts? I read you can cause damage to tran and diff by overtightening them. Do we have a torque spec on the bolts?

It is the spread of the clamping weight over a larger area instead of just under the bolt head. Every stick car I have pulled the beam out of has had the trans end holes elongated even though the bolts were tight so something is moving.
The key stock was a good idea.
I wish I could sell all of those "beam plates" that I could make for $180 a set. I would be retired and living in Hawaii inside of two years.
