Diff Ratio.........

[THUNDERVZ]

Have a 2006 vz thunder s manual ute,what should the diff ratio be ?

[Kiddo]

3.45:1....i think

There should be a little metal tag on the diff. sus that out cause it has the ratio on it

[THUNDERVZ]

checked it out 2.87 on tag......................

The V8 Thunder manuals have 3.46, 2.87 is correct for the V6 a change to 3.46 will definitely wake it up though if you after better performance without really hurting fuel economy.
