What kida of weight are you towing? About how much do you weight. Seems 5:29's might be a bit much, fuel economy may suffer, but it is an 80, so anything over 10 mpg is ok, I guess! I do not drive much over 70 mph so it may not matter.I also run 35's and originally, I would have put 4.88's in because I read somewhere, possibly in this forum, that that was the best setup. However, Zuk suggested 5.29's because he had gotten enough feedback from his customers that they wished they would have gone with 5.29's. I pull a trailer when overlanding and it works great, except for the long highway passes. The only other down side is when I do 80 on 80 in my 80, it really pulls the revs That's an inside joke for those that live near I-80. (80 mph, on I-80, in my 80 series). But seriously, after running 33's and upgrading to 35's with stock gears for a while, when I was done with the lockers and new gears, I got the pep back in my 80! And off road, it was even better.
I'm OK with 70-75 mph on the highway:
