Rear gear ratio suggestion?

[ShredSled]

Ron is a vendor here. I finally found them online, but still not from Motive or Yukon. Regardless, thanks for sharing. Now I'm not so butt hurt that I can't use them.

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

What gear ratio are you referring to above?

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

What size tire are you running? Do 4.30s! I don't think your highway would suffer and should really help your city. Check my "$$ gear install" thread, someone posted a link to calculate your cruising RPMs.

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?

[Crazy Blu]

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.
