Does anyone know when they changed to the new streamline version? Do they have billet top caps? Do all of them (old - new), have the billet cap?

Thanks,

Bob

Bob,
the new design came out last year sometime. The new case comes with a cap, that isnt billet but it is much thicker and has a steel tower in it. It can be used on the old case, but need to be shimmed accordingly, for proper setup..

Hope this helps.

does any one know if the new cases are stronger?

not somuch stronger a little better design and harder to set up, one thing about merc when a patent is about to expire they change the design enough that the parts will have to come from them ie: gear changes 1.5 they changed to 1.47 ect guess it was time to change the housing

Thanks for the info guys. I didn't think Merc. would use a billet cap on that but, you never know. Looks good and beefy though.

I haven't seen the 2006 XR drives, do they use the same cap on them?
