| Post subject: | Matching gears |
I know we're suppose to match gear ratios front and rear, but I'm interested in purchasing Jeepin by Al's front steel diff. Since I have 4.10 installed now I was hoping I could get the same setup for the front, but JBA only has 4.11 gearing in the front. Does the .01 make a difference? I'd love to go with lower gearing all around and the steel diff, but I don't have $3K or more to burn right now. |

Your actual front diff gears(the ones in the D30A) are 4.09's,not 4.10's. There is no such thing as a 4.11 gear set for a D30. |

The difference between 4.09 and 4.11 is very small, you wont notice the difference. Tire diameter differences between your front and back tires is probably more. |

Eggzachery. Factory 4.27/4.30 combo's were used in many apps and are well within acceptable standards. Go for it... |

I have 4.09's in the front with a diff pulled from a 4 cylinder and Yukon 4.11's in the rear. Has been like that for many years and works perfectly. |

Excellent. Thanks for all the information everyone. Now I've just got to wrangle up the money for the steel diff. |
