Yeah, I hear you on that. Except for my squaredrop off road trailer, most of my towing is done with my 7.3L Powerstroke F350 now-a-days. And my 1st choice was the 4.88's when I started the upgrade to my 3rds. But after explaining the future use of my 80 to ZUK, who did the upgrades, he convinced me that 5.29's would be a better choice for my needs. He told me that he was amazed at the feed back he got from other 80 owners that he'd done their 3rds. A significant number of those that did the 4.88 wished they went with the 5.29. 4.88 is the ratio that puts 35" tires closer to OEM gearing, but so what?!? Many complain that the 1FZ and it's stock ratio sucks on hills. Some have gone the turbo route and say it's a different animal. I may do that if I ever rebuild mine. I'm above 295K now so it may not be far off.And by choice, if I had to tow, an 80 wouldn't be it.
