Precision Gear vs Yukon?

[Timstrk]

SOME of the gear sets were 4.10/4.11. The 170 6 and some of the 200 6 had those. I don't know of any 289/302 that came stock that way. The reason it broke may be because of a mismatch between front and rear. I had a set like that once. Do check the rear before assuming the rear is 4.10. There can be mismatch front to rear but not in the 3.73-4.11 range. That is too much. 4.10-4.09 F-R is ok and accepted as equal. No pavement is the only stopper there. Dirt will give up that difference.
