Ultravan Owners Posted March 25, 2017 Share Posted March 25, 2017 (edited) My hope is that there are some members out there with the vehicle(s) I need the info from. I need the following information on 2010 and up with the EZ36D and AUTOMATIC only!! 1. What is the rear end final drive ratio? (I already have the ratio in the trans itself) 2. What size FACTORY tires are used on the same vehicle? (found on factory sticker) 3. What year and model vehicle do you have? NOTE: The above information will help me run an Engine RPM and Speed Calculator to make sure my planned build will be able to run in the factory sweet spot or not. Thank you for your help and time. It means a lot!! Sincerely, Tony Edited March 25, 2017 by Ultravan Owners Link to comment Share on other sites More sharing options...

Ultravan Owners Posted March 25, 2017 Author Share Posted March 25, 2017 (edited) Thank you very much. As long as the FINAL Drive specs under the transmission section is the same as what the REAR Differential ALSO has - I have figured out another step in the process that I needed.
