If anyone has a gen 4 diff and they want to upgrade to the 9 inch.

I may be interest in the gen 4 .

The maggie will probably blow your stock rear, then you won't have the money for the new rear.

Life coach?! Investor?!

Life coach: you are a life coach? what happened to practice what you preach? your personality and attitude do not match since you are supposed to be motivating people not putting them down because of their career choice. Sorry that not everyone's parents set them straight financially early in life.

Investor: Then you should understand that a $5500 investment to have the ability to dump the clutch in your 4000 lb cadillac isnt really a high priority. To actually need that much support in a differential, 700-800 HP minimum. The Gen 4 diff for $1500 ($4000 less if your math is a little off) is a screaming deal for what most people use these cars for. Road track and street driving. Not 1/4 mile strip runs.

But since you have more money than common sense, you will stick to your imports in a country that is coming out of an economical depression to help boost the stock market to further your investment value? Doesnt make sense there guy.

I forgot what it was like talking to the upper class inheritors of their parents and grandparents hard work! They have no appreciation for the world they live in nor understand the real value of a dollar.

Ok guys,

I need you guys that are serious about getting this swap to either email me, PM or call with your contact info so I can get you in line for a kit.
I have the 1st slot filled and probably the 2nd and 3rd slots but let me know please. This will help me plan for production.

Thanks
Chris

Like me, bone stock and the car has never seen the track and lost 1 diff already. Car only had 35k miles on it.

Any idea of what the weight difference is yet? Waiting on your post install reviews to be quite honest. I would like to see how much power people are losing through the 9" as well as the handling difference. I am still feeling like an m44 viper rear might be a better choice. Waiting on you guys...

Id like to see some reviews as well before throwing my name in there. It will be good to know down the road that if i wanna go to the track and blow my stock rear that this is an option. Thanks for putting it together i look forward to seeing it in some cars.

How much of a role does the gear ratio play in hp? I dont see why someone wouldnt do a built rear strictly because of a small loss in hp.

The weight of the rear I'd say is the MAJOR issue that I am worried about. It looked like a steel case to me. Did some research on Viper rears and people are making 1000 to the tire and it holds all day, and it's cheap. UPDATES??

While i understand the debate of all the different axle options out there, it is a moot point in this thread, Geforce is making a 9" rearend... and is far enough in that he is not changing that now.

Right now your options are stock diff, this 9" once done, or whatever you want with a ton of fab work....

I'm not saying that there are not better options out there, but i am just happy that somebody is stepping up and making a strong rearend for us. (i quite frankly will give up some weight and power to know i am not going to break the rear.) I love drag racing, and want to be able to take this out whenever i want without thinking twice. Plus this is not just some guy in his garage claiming he is going to make this work, and sell them, it is a proven company that makes some of the best products on the market.

Lets not look a gift horse in the mouth

Then do a viper diff swap, post a thread and let us you how much it costed and details of the work involved.

Other then that stop bashing the 9", if you dont like it don't buy it . Simple as that.

The above Moser M9 Camaro/Firebird rear with the optional Moser alum center section is the same weight as the very light and flimsy Camaro/Firebird 10 bolt oem rear that comes in those cars. My Z28 ran a 9.12 with the first one of these M9 rears. I am showing you this to point out that just because G Force is using a nine inch doesn't necessarily mean that it is going to be heavy. Bob

The stock V rear weighs 55 lbs and our fabbed 9" rear comes in at 85 lbs. or about 70 lbs with an aluminum center section.
A 15-30 lb weight gain. Not much considering the vast improvement you'll be getting.
Dont forget you'll be able to change out gears for dirt cheap. Alot of guys that run 9" rears will have 2 drop out pumpkins, one with say 4.56 gears for the track and one with 3.25 gears for the highway. Since the 9" is a drop out style rear, all you have to do is swap the pumpkins out and your done, no setting up the gears or anything.

For those of you that dont know anything about a 9", you set the pumpkin (the center section part) up on a bench and then you just bolt it in the housing. Very easy to work on.

Here is the pricing.

$5562.

Here is what you get.

• Fabricated bolt in housing
• Powder coated to what ever color you want (Black is standard)
• BMR heavy duty bushings.
• Strange Engineering Pro Iron center section w/gears and Truetrac installed and set up
• 3.5" Aluminum Driveshaft (Add $400. for Carbon Fiber)
• 300m Axles and stubs

Thanks

Same price for aluminum center section?

I'm sure I'll be needing one soon too. I bought it at 40k and it now has 60k. According to GM, it got a new rear at 11k miles. I've put 12 passes on this car when it was stock. I have only wheel hopped the car once just to see what it felt like. It seems like the rears that are not beat on seem to last. I will be a customer of this rear soon too as I plan to keep running this rear until it blows and will worry about upgrading then..lol.

Sure it is over kill for some people, but it will take anything you throw at it.

The aluminum centers are like $100. more if I remember right. Might be a little less.

Thanks

Can you elaborate on the driveshaft design? Are they going to be U-jointed front and rear, with no center bearing?
