yeah, I don't think Yukon ever made any, but mine are no doubt Motive's.

4L60E overdrive, 4.56's, and 31" tires.

That was me :badteef: haha

Thank You for the info.

Yup! I would say go with a 4.56 for that tire size. It would put you at about 2,300rpm at 70mph with the 60e overdrive.

Revisit...

What size if there is a strong possibility of a future turbo install?

3.90s

Depends on the size of the whole setup Jason. I have 3.42s with a small stall in my 4l80e, and I cruise at like 1900-2k at 70-80. Its pretty nice. With a bigger stall I would still stick with my 3.42s. A lot run the 3.73 range for an all around good gear as well.

I'm also running 33" tires. Was looking at the Trick stage 3.
