What upgrades did y’all do for your rear differential to handle 600 + hp with no sweat?

Moto-Mojo · 04-24-2021, 11:09 AM

I’m thinking most will say upgrade to a ZL1 diff and or whole cradle. But I’m not the resident expert.

AlanRubin · 04-24-2021, 11:29 AM

The whole cradle would be nice, depending on the condition/miles of all the other
parts.

If its an auto not much. Maybe am eaton posi. Pretty strong rear honestly

Batmanntexas · 04-24-2021, 03:28 PM

Agreed, the ZL1 setup would be ideal, however, if budget is an issue, a TruTrac would be a good upgrade over the stock differential.

I did nothing but 3.91's and ran lower 11's easily.

TheFlyingBananaSS · 04-24-2021, 04:32 PM

Who knows what will happen this season. I am over another 100whp on same setup. Call me the test mule lol.

Im almost finished with mine and ill be right there with ya lol. Testing to see what breaks first

People were doing all kinds of voodoo to make the 10 bolt last when these things first came out, but if you're not going ZL and need extra strength, put in the TruTrac carrier. Then you can just buy axles.

I don't think the rest of the internal mods merit the cost.

My new mantra... SEND IT!!!

If it breaks, oh well.
If not, cool.

Now that's a realist, modder attitude! You have to be willing to accept all outcomes. (and it doesn't hurt to be well funded either)

ZL1 and 3.91's you will not regret it.

You cannot put 3.91 gears in a ZL1 differential.

Fixing the wheelhop will give a longer life to your axles and diff.
