Unfortunately I have the standard z06 ratios so the 4.11 help bring my 4th/5th gear up to something more useful.

It is mainly for when I go to mexico and find exotics to play with - they pull away huge once you hit 4th and it is over from there.

As an example here is a Mclaren 720:

39T on the ring and 10 on the pinion, pinion fits on the Z06 output shaft. Checked just to be on the safe side.

Some of the GM/ Kent Moore tools will remove the bearings without damage, just have to see. Personally I would replace.

Expensive compared to what?

kent Moore speciality tools $2000
snap-on tare torque wrench $330
snap-on 400ft-lb torque wrench $950

Spare Z06 diff $700
3.90 Motive gears $640

at this point what is a couple of hundred to do it right? Just my opinion

personally I have a lot of pride doing the work myself

My local contact charges 275.00-350.00 to R&R the gear set. He was the master corvette tech at one of our local dealerships, and did most of the rear end work , so he has the tools and the experience to setup a new rear

Can these only be used in the Z06 Rear and not for ZR1?

Damnit! Now I have to spend more money lol I'm gonna wait until I hear some feedback though on the noise etc. Motive has had some quality control issues in the past. Hope they work out great for all of us!

Received my 3.90 set yesterday. Can't wait to get these in the car. Would be going from a 10.47 Starting Line Ratio to a 11.93. I currently sixty foot consistently in the 1.31/32 range and these gears should easily make it a 1.2x sixty consistently with a 28" tire! All on stock suspension!

Damn auto cars !!!!!

Looking forward to seeing what you can do with the new gearset at the track. I have a few friends now going 15" conversion in the back with 4.11's, so it's going to be interesting how much their 60' drops are and what MPH they will tack on in the traps.

Indeed we did - let's hope Motive QA doesn't make us regret early adoption.
