Changing gear ratio

stateofdade · Sep 18, 2019

When I swap from the 3.21 to the 3.92 in my 2wd, what else do I need to supply (bearings, etc..) to the shop? I know I can save a good deal purchasing the parts myself. I want to add a high end oil to the rear end at the swap too.

Just buy a rebuild kit should come with everything needed for a correct install.

Contact Matt@Moe's. He'll have everything you need.

I love my 4.10s. I got everything from Matt. Do some form of Limited Slip Differential, while you're at it.

I'd like to hear all about it when you're done.

I sent an email about it over a week ago but waiting for a response. They're probably piled up with requests.

Did you swap from the 3.21?

State, I had 3.55s. However, it was in a 5/6 speed.

I'd skip the 3.92s, and go with 4.10s. But that's just me...

Almost everybody that has geared down, was very happy with the results. There were a couple of guys with the 5/6 that felt they should have gone with 4.56 instead of 4.10 because 4.10 wasn't low enough for their application.

You'll be glad you got rid of those 3.21s, I'll bet!

No better advantage than mechanical advantage.

CALL Matt. I'm old school. I like actually talking to people. And cash is king.

I think he is dealing with all that rain from the storm over Houston right now. I think they were expecting about 10" of rain. You might give him a day or two to answer you---
