Read 'a smaller gear will increase acceleration but has lower mpg.'

I read it twice, last sentence of the first long paragraph... Have I been working under all the wrong assumptions for years!? Higher gears have better mpg and top speeds?! That link is tarded, I wouldn't suggest using that as a learning tool.

Re: How can you tell what rear end you got?

you can get the info right off the diff. on the white sticker(s) or you can de-code it by the numbers on the sticker in your door. I can decifer it.Just don't have the info in front of me......but a example and do not think this is accurate,but, BB=3.73
