WillieB Posted March 9, 2020 Share Posted March 9, 2020 I like TFL a lot. They have some great vids. They even tell the difference in a 3.73 and the 4.30 gears as around 1mpg less with the 4.30. I'd say well worth it to get the additional towing capabilities. Only prob is they will be hard to find unless you are ordering new. Quote Link to comment Share on other sites More sharing options...
Aufwand Posted June 24, 2020 Share Posted June 24, 2020 Did they test a 7.3 with 3.73s vs a 7.3 with 4.30s? I need to watch that vid. Quote Link to comment Share on other sites More sharing options...
