So wait, you can move our LSD clutch packs into a rear 4.77 3rd member?

You need to bolt the ring gear to the LSD carrier, (where the clutch packs live)

Then you will have to have the gears set up by a pro.

Yes, and not only that but I went on search overload when I found out that a turbo Isuzu Impulse had a 10 bolt LSD in the rear that will fit perfectly into a set of 4.77's on the front of the VX as well ;-)

All the junkyard Impulse Turbo's that I found were missing the diff though :-(

That's a 1.6" increase on the radius (about 10% reduction in accel). I think? Seems to me that would be very noticeable.

Today, as I was running errands, it came to me...(light bulb moment)

The difference in acceleration feels to me, like about the difference between the A/C off vs A/C on...but just a little better.

Are you running 33's with stock gearing?? I always have A/C on in the desert.

Dude...:confused:

Did you do due diligent research? (as in : read the thread)

I'm roll'n 35's & 4:77's...:smilewink

Also, the fact that you always run your A/C, isn't germane to my statement...:_thinking

I was trying to explain my perception of the difference in acceleration between stock & 4:77 gearing...:fyi:

I have 33's w/stock gearing. I like LDubs analogy about the A/C.
BUT, i realized a caveat recently. It depends on exhaust! When I posted that the off the line feel was not that different than stock, I had a much more open exhaust than I do right now. Back then I had a Cherry Bomb Vortex muffler (similar to Flowmaster 40). Recently I added a SuperTrapp with 24 disks to tame it a little. It gave better tone and higher RPM torque due to back pressure increase, but low-end torque dropped a little. It bogs SLIGHTLY from a stop if throttle is aggressive. Once up to 2300ish RPM and WOT, it screams (as much as a 3.5 can...).
But, less restricted... yes, much better off the line.

Who's not reading? My question was directed to SilverBullet75. And I got your comparison, but seeing as I run with the A/C on all the time, that would be double s**t for me. Air on and stock R&P with 33" tires........get it? Double s**t, Maddawg driving around with the windows down in 105 deg temp in order to gain acceleration, lol. I do diligent research all right, I just have CRS! But thanks anyway!!

Thanks SilverBullet! I just went back to a stock muffler after going half deaf with the Flowmaster 40. The only experience I've had with the SuperTrapp was on my Baja and my dirt bike, I think I was running about 12 or 16 discs on them. Just talking ya know.

Check the tude at the door please...:smilewink

I replied in a effort to relate my perceived difference between stock & 4:77's...you know, to help you out.

If you had actual comprehension of what was said, you would be able to figure out that the DIFFERENCE in acceleration, with & without the A/C on, is what I was referring to...you DO know that acceleration is slower with the A/C sapping some of the power...right?

:fyi:...You quoted me when asking this question...so I thought the query was directed @ me...:_confused

If you even had comprehension of the TITLE + author of this thread, you wouldn't have quoted me, OR asked that question.

Can't hardly wait to be of help again...
