Were putting together a 1990 xj race jeep. Were going to run 4.56 gears in a high pinion d30. What are the strongest gears available? We would run Dana gears but they don't come in 4.56. Any suggestions?

4.56 was the factory ratio for 87+ 2.5/AW4 jeeps, so there's a Dana-Spicer part number

most failures are carrier related and not gear related.

you're overthinking it a little.

and i hate to say it, should build a dana 44

yep. carrier flex is a big problem on the d30. what kind of racing are you talking about that you think you might blow the gears up? in the desert this won't be an issue...
