Stampede - I think it's the Diff Plates (look like this)

Thats them! laser cut and ground!

think you may of been better off with a hardenned steel, Titanium, I don't think will take the loading.

Ive fitted some in mine so ill give them a test. titanium is harder than steel and less brittle than hardened steel the only real drawback is you can shatter the balls in the diff if you set it up wrong.
It doesnt matter if these sell or not i had to use the matterial to get my moneys worth so if anyone wants a pair make me an offer.

That's a pretty bold statement... Titanium isn't necessarily harder than steel, it depends very much on the grade of both materials.

As for the resilience, it is not an issue at all as there are no shocks on a diff plate.

i thought titanium had a poor wear rate?

Titanium is strong, but not hard wearing.

I would hope it is ats the same material at areo engine components are made from a know as its an off cut!

Its not just a guess mate im a qualified mechanical engineer i do know my stuff. im just not sure how it will take to the car but i do know that the material i used is top quality stuff.

hi, just wondering how the Ti diff plates were going? Ti is funny stuff, very brittle on its own but alloy'd with other materials such as aluminium, vanadium, copper , zinc and many other things it can be transformed, love to hear the how they go, ceramic diff balls, Ti diff rings , all rotating mass that will be reduced.sounds good to me if they last, .;)

how are they doing, good or bad?? i have been doing a bit of research on Ti and under a very powerful microscope Ti (6al4v) looks like it has a very rough surface when compared to steel alloy, this would explain the shattered diff balls ,,do you know the composition of the stuff you used for the diff plates, should be easy to find out as aero parts are very specific with regards to what alloy is used where.

Sorry to be the minus-man here but Titanium is almost never harder than steel and the hardest ti alloys are nowhere near hard enough for diff plates. It's a great structural metal, especially when strength in high-heat conditions (the SR71 spy plane is almost entirely Ti) is important but it is never used for bearing applications because it has low surface hardness and a high coefficient of friction. Ti-nitride coating on steel might be worthwhile (like gold shock shafts) but would probably just wear off quickly.
