ID like toAwesome! 4.56’s seem like a sweet spot for the 350.
I would like to hear from others on the forum here who have done this swap. Anyone else changed over to 4.56 ratio? I am close to pulling the trigger. I have a specialty shop a short drive away who will do the job.Awesome! 4.56’s seem like a sweet spot for the 350.
Do you know the MPH at redline for gears 1-5 with the 4.56?Here is a more complete “GEAR / MPH / RPM” chart for the 4.56 Rear Gear
Awesome. So redline in first only moves from 55 down to 50... that's less than I would have thought.I adapted this spreadsheet from another one I found on the 'Net...

Agreed, but seems nobody else has done this swap yet!I am very impressed with the content of this thread. Big thank you to John Vallo for being such a pioneer in Yukon gear swaps. Now I know where to get the Yukon gears from and how to install them. Very thankful to John.
