It induces plastic deformation of the grains on the surface of the aluminum. Puts it under a compressive stress. Kind of like tempering in glass.

Its a hardening process that is used for strength. Makes the aluminum harder, but more brittle.

I bought a new 2.0 last week. I also ordered a spare of almost the whole car. I knew the shock towers had some issues. I went out and looked at the shock tower that came on the car and then compared it to the new losi replacement tower. It's the same part number but it is thicker for sure. Looks lime the same design just thicker at the top where they have been cracking. So im sure the stock losi tower is just as good as the KH tower now that they addressed it.

Yeah but the KHZ tower allows you to get rid of the silly little plastic caps. It also looks trick. IDK I have alway's had great luck with the KHZ stuff. Plus that way you don't have to gamble on weather or not you will be getting the new model.

I ran thier towers on my 8T 1.0 for over a year. They make a great product. I wish I had known they were going to come out with the hubs before I bought the losi aluminum ones. But I got mine modded by J-DUB so they are basically the same thing as the KHZ ones. So far so good with me too.

Edit: thier towers also resolve the problem with camber link and wing mount screws being too short. The KHZ towers are machined down like the losi towers always should have been. The buggy only has the problem with the rear camber link screws, but the truck has it with all 4 camber link screws and the wing mount screws.
