I can get a set of new Dana 30 4.10 gears AND a set of new 8.25" gears that a guy was going to put in a cherokee. Will the 8.25" work in our axles? Also, will the dana 30's fit in the Dana 30a (and the Dana HP30 that I will swap in later)? I can get both sets for $150... they are still in the box. Rescu2000 |

You need to know if the XJ has a 27 or 29 spline rear end with the KJ being a 29 spline. The XJ could have either. As long as the gears are for a 29 spline Chrylser 8.25" they will work in the rearend. The D30a's ring and pinion is just dimensionally different that standard D30 gears will not work. Something about the length of the pinion I think? |

Yea, the pinion is about 1 Inch longer. I just don't understand how these things work well enough to know that the longer pinion would cause the gear not to work. I should pick up the 30 also though, just to drop it in when I do the axle swap. Rescu2000 |

It's a 93 cherokee that they fit. It looks like that is a 27 spline. Drat! I would have bought both of them. I found a Dana 30 SFA for $50.... |
