Since my post on here, I learned that we ordered 4.88’s. Not sure what happened. Anyhow, we finally got our hands on five 40x15.50R20 Toyo’s. So as soon as they get in, and the shop is cleared of its current project, we can finally (2 years later) get this Jeep built. Now as for the 40’s and 4.88’s, we’ll see how she performs and see if we need to change them.So I have my axles. Started the build then FedEx lost my driveshafts… I went with 5.13. Going to run 40’s for the first set. Next 42’s.
I’m building at a friends shop. While waiting I’ve put over 600 miles on his JTRD running 42’s with 5.38 gearing. Drives close to a stock JTRD around town and up to Freeway speed. Freeway speeds (above 65) would be the only issue for some that do not want to cruise above 2K RPM. Cruise RPM is about the same as a stock 3/4 ton Duramax. I owned many between 2000 and 2010.
This JTRD has over 15k miles. No issues.
Edit. On the return trip from NorCal to AZ. Approximately 500miles. Average speed 70mph. Approximately 2250 RPM. 18 MPG. Speedo correct. GPS verified. JTRD 5.38 gearing. Nitto 42” tires.
Patients is a virtue said no Jeep owner! LOL!
