TRD PRO Gear Ratio?

I dont care about mpg!!! Give me power!!!
4.88's baby!!!

 

I am sorry but I have to ask. What were all of you guys talking about on this thread?
What's all this ratio stuff y'all were mentioning were different between the two models and all those numbers mean?
I'm sorry to be annoying sometimes asking newbie questions, but I didn't get a chance to ask at that time, I didn't want to interrupt all your serious discussion with me and my silly questions. I had this thread open in a tab for several weeks, and just finally got to it.

 

Gear ratio in the axles.
3.90 ratio is, for every 3.9 turns of the drive shaft one turn of the tire.
If you change to 4.30 then drive shaft turns 4.3 turns for every one turn of the tire. Thus making more torque and raising rpms. Putting rpms in the power curve where it should be.

Hope that helps..

 

4.30 gear ratio for Manual trannys and 3.90 for the automatics... M/T FTMFW! Just sayin.

 

Thank-you, I understand now better.
