Alot thicker lol. I would still go with the KHZ tower, especially with all the talk about the losi towers being cast then CNC'd.

Not sure but a guess from the picture would be 4-5mm.

pretty easy to tell em apart..looks thincker and less machnined out on the top

thanks!!

All aluminum is first cast then cnc'd...it just depends on the grade of the aluminum there getting there blanks from..they deffinatly dont machine it straight out of the ground!!

well yes, but there is speculation that the towers are cast, and just cleaned up with the CNC. Not sure if any of that is true though. I would hope they are actually 7075 alloy.

A buddy of mine broke a KingHeadz shock tower and the look of the material structure inside looked the same as that broken losi in the earlier picture.
I have a 1.0 truggy tower that is bent. I will try to go break it and see how it looks inside. I will also cut it in half and see how the material looks. Alot of the appears of the material inside, under the CNC finishing is dependent on the process the Aluminum is forged.

ill be shocked if it is really 7075..and not somthing a little cheaper like 2025...The chasis plate has the same weird "texture" on it..like the chasis plate is textured aluminum..the black anodizing feals like spray paint!!! HAHA..regardless i love my losi cars..There like a sore peater.. you cant beat it

pretty much all fractured aluminum parts have that same "cast" look on the inside..its all about the material and how its machined or forged that makes the difference..

I have not gotten the king headz front shock tower yet should be here tommorow..are all the shock location holes in the same place?

The KH towers should have the same geometry.

In this photo, I took an old 8ight-t shock tower, cut half way through and then broke it the rest of the way. The cut area provides a smoother, machined surface such as the CNC finishing. The broken area looks like the "cast" metal as some are calling it.

http://img.photobucket.com/albums/v2...o/100_2013.jpg

Regardless, the towers are breaking because they are too thin, not whether the material is cast, billet, or forged.
All Aluminum starts as a cast. The virgin aluminum is melted and alloys are created during the casting process. The aluminum cast is then poured into either a billet of varying diameters and lengths depending on the cast house, or smaller cast pours. Forging is the process of then taking the aluminum billet and using many tons of pressure to forge aluminum into a specific shape. Doing so makes the aluminum extremely tough.
In my opinion, the material used to make the shock towers is likely a billet that is heat treated, rolled to certain thicknesses and made into a sheet of aluminum. The sheet of aluminum is then cut into smaller sections that are easy to chuck up in a CNC. Machining a shock tower out of a virgin billet would not be cost effective at all.

None-the-less, Losi has corrected the problem with thicker towers. It does suck that when we order or have one ordered, we don't know if we are getting the thicker or thinner though.

The chassis' are shot peened. That is the reason for the textrue.

Yea, the shot peened surface of the 1.0 was awesome. Same way with the shot peen of the 2.0. This is to relieve the surface tension right? Or something like that. I'm not sure cause I'm not an metalurgist.

Yeah I really don't know why it is either. There must be some reason, but not sure really. I would assume it makes it tougher/ more durable. I know the losi chassis' are pretty tough as far as wear goes.
