Assuming you have a 4L60e trans? what RPM are you at running 70 MPH? Looking at what to do with my 3.42 gears on my 94 Suburban. ThxGoing from 3.42's to 3.73's on a 29" tall tire really woke the truck up.

1500 rpm = just slightly over 70 mph. 71? 72?Assuming you have a 4L60e trans? what RPM are you at running 70 MPH? Looking at what to do with my 3.42 gears on my 94 Suburban. Thx
Wow really! I am running more rpm than that with my 3.42 with 29" tires. I want to say I'm at 2100 or so.1500 rpm = just slightly over 70 mph. 71? 72?
I'm putting 33s on 18 inch tires and have a 4l60e transWhat size tires are you running? I have 275/60/15s on the OE rims, with 373s and an Eaton trutrack. Love it. The bigger the tires, the lower gears you need. Also what trans do you have 373s do good with a 4L60E, it a 700R4. 1st gear, is low in those transmissions.You must be registered for see images attach
You need a low gear ratio for 33 inch tires. Probably around 456.I'm putting 33s on 18 inch tires and have a 4l60e trans
Doh! My math was off.Wow really! I am running more rpm than that with my 3.42 with 29" tires. I want to say I'm at 2100 or so.
