Had my 11 2 door up to 101 mph with the 3.73 gears on stock 32 inch rubber. That was in 3rd gear as I have the four speed auto and it would run faster in third then forth as it powered out. It is saved on my nav as it stores your fastest speed. Now I have 4.88 gears and still on stock rubber and will run over 100 easy in fourth overdrive gear. I may never go bigger tires as the jeep is very spunky and does 80 at 2800 rpm. Before it was 1900 rpm at 80 and a dog. I test drove a new Rubi with 3.6 4.10 gears and it felt like a dog compared to my 3.8 with 4.88 gears. I often cruse 80 all day long on the big road from Kansas to Vegas at 2800 rpm and with 30 K on the 3.8 she has never used a drop of oil. 5W30 Mobil one since new. Love my 3.8! When I want to go fast I drive my Shelby Raptor with 600 hp and factory 4.10 and 35 inch tires. Fords rock the desert like no jeep can lol
