my 4.56's are in

[Onebadbee]

making an appointment to get them installed this week

Mine are sitting here too, now I just need to find time to install them. I have to grind my case to get proper ring gear/ case clearance on my 07. I think your 05 just slides right in other than grinding the cross-pin. Should make a noticeable gain for both of us.

Btw, my next mod is a 4l80e swap. I've got the money just need to get a used trans to build and the associated parts.

That is why I will be looking at the yukons because from what I hear they do not require grinding.

I installed Yukon in my '06 and didn't have to grind anything. I also installed a DTT at the same time.
