Thats a good question. From 4.10-4.56 isn't a huge jump. But will likely get you 10th back. When gearing up you have to consider your priorities and usage case. The more aggressive play is 4.88 If you want more low end grunt to climb and tow and just overall have more snap off the line, run a lot of sand and want more wheel speed? go 4.88. It will be at the expense of some fuel milage and higher rpm’s on the highway( or as you mentioned drone). 4.56 is a bit more mild, basically restores final stock ratio to lock out in 10th. Fuel milage might actually improve. But idk what your goals are.

I will add, this is the unsung beauty of these new 8-10 speed transmissions…. Even without a regear they adapt and compensate really well. Back in the day with 4/5/6 speeds you were cooked!

Since this thread has had a TON of great info thanks to Geoff I wanted to add one more tid bit. I was at Suncoast yesterday and we did some experimenting. Their billet 10R80 flexplate (that they usually market for Coyotes) is a direct fit for our 3.5’s!!!! Also, the Coyote ARP flexplate bolts are a direct fit as well! Drove mine 200 miles on the new set up last night.

Not trying to sound like a corn dog but if you guys need transmission stuff I really haven’t ever worked with a company that I like better than Suncoast!
