Debating on wether or not to run a moser 9 inch or 12 bolt with 33 spline axles and 3.73's what buy would be better? what are the pros and cons of both? just looking to have a strong yet streetable car. putting down 430 N/A H/C/I LS1 WS6

Why not a S60 just curious? I can get you any of the rearends of the 2 you mentioned the 9'' is going to be the strongest the 12bolt of over time tends to want to make noise if you have a car with decent power. Is your car a 6spd or an auto? If you have any questions please give us call and we can answer any questions or concerns you might have.

Depends. 9 inch has more gear ratios available and is probably easier to swap them. Cons are it eats more power. Im a 12 bolt fan, im running a Strange unit. However I realize it's not for everyone. Long term goals and car usage would be paramount in my decision. A 12 bolt can handle a lot when built right, will you ever out grow it? Will more gear choices ever really benefit you? How often would you change them? If the advantage of a 9 inch isnt worth it, run the 12.

with the S60 wouldn't you have to modify the shaft or something? if so what modification would need to be done to it?

The S60 is a direct bolt-in, no mods needed. If you are concerned about the driveshaft the general concern is if you have the need ofr an aftermarket rearend you sure need an aftermarket driveshaft as well. The factory shafts are weak at best and will cause 100s of dollars more to repair the costs of the damage it can cause if a failure happens, then you still have to replace the shaft!

Call us for the absolute best deals and tech help on any rearend package, whether it be a 12 bolt, S60 or 9"!

If you need an aftermarket rear to hold your power, you most likely need a better d/s as well. Do you take it to the strip or is this more of an auto-x/road race car? 60lbs of extra unsprung weight would be obnoxious from an s60 if you're interested in handling.

Sorry bud but Im busting *** to trim my car down (for drag) and you better believe I would not want to throw away 60 pounds for essentially zero benefit. **** that heavy *** rear end.

Hot Rod Mag rear end comparo, S60 is 17lbs more than 9 inch and 20 lbs more than the 12 bolt.

OP, keep doing research, there's a reason Strange Eng, Carl at CRP and Bob at brute speed don't push the 12 bolt.

I was thinking in my head 60 was probably not accurate. Perhaps between an s60 and a fab9 that would be more accurate.

We can build our fabricated nine inch to be lighter than a stock 10-bolt and still be the only rear end on the market to bolt back in just like the 10-bolt came out. With these types of weight savings also eliminates daily drivability for parts life. All though one of the top sellers was aluminum cases and spool and I have yet to get complaints from customers today.

Stamped housings are heavy no matter how you slice it, the 10-20 pounds between them is going to effect outcome as much as drive-train loss between them all. Which is next to nothing on your average vehicle.

That's why I said it would be obnoxious

Central Racing Parts Fabricated 9" bolts right back in just as the 10-bolt came out. It is also better designed, stronger and sold by a company with an excellent reputation.

I took that as obnoxious for the road racer, not necessarily for drag. At the end of the day one small thing like that might not make a huge difference. However, if you're selecting the lightest and best parts throughout your build, then at the end of the build, the difference WILL show.

Willzm throws his car on the back bumper and goes 9.4s with his s60 and hasn't had a problem with it. So if you are on a budget the s60 is hard to beat.

There is no doubt that we have always said the S-60 was the next best option behind our fabricated nine inch for a F-body. It has proven to be a very durable rear end option.

We still sell a bunch of them but it seems most of our current Midwest Chassis fabricated nine inch customers are those replacing what they bought years ago saying they wish they would of just purchased our fabricated nine inch to begin with.
