I am looking to purchase a 12 bolt to replace my 10 bolt and was wondering who has the best deal on them? I am not really sure If I want to go with a posi unit or full spool yet. i realy don't drive the car that much its not a daily driver just good weather and when I fell like it. I have seperate wheels for my drag radials and seperate wheels with regular street tires. I will be looking for one with 373 gears and I guess 35 spline axles due to the price being the same for 31-35 spline. The car only makes 450 rwhp with another 150 hp of nitrous and is a stalled auto so it doesn't have to be bullet proof. Thanks for any input you guys can give.

Put a 12 bolt into a early Chevelle, Nova, Camaro, etc and you can beat the crap out of it, and not hurt anything. Put one into one of our cars with a torque arm, make a couple 4000 to 5000 dragstrip launches, and I can just about guarantee you'll pick up gear noise. If it is a drag only car, you'll never know or care about the gear noise. Drive your car home from the track, and the noise will drive you nuts. I feel the torque arm stresses the 12 bolt housing, causing distortion. We have never seen this happen with the 9 inch housing.

Exotic Performance Plus strongly recommends the Moser nine inch. This rear is even tougher than the Moser 12 bolt, and the horsepower of the late model F Body cars keeps escalating every year, which requires a very strong rear. With the recent introduction of the 6.2L GM aluminum block and the excellent flowing 6.2 litre heads, the horsepower of these cars is going to just keep climbing at a very fast pace.The nine inch will handle the power, plus we prefer the way the torque arm is bolted to the nine inch in the same way the oem rear-end is attached. (This is the only good thing about the stock 10 bolt...) The Moser 12 bolt uses four short bolts to attach the torque arm, and they have a habit of loosening up, even when loc-tite is used. Why the nine inch is stronger than the 12 bolt. The 9-inch has an internal rear-pinion support that also supports the gear end of the pinion to limit gear deflection under high torque loads. This seems to be the major reason why the 9 inch doesn't start whining after high rpm clutch dumps, when the 12 bolt will pick up noise.The 9-inch locates its pinion gear lower on the ring gear to improve tooth contact, than the 12 bolt does.The 9-inch has a 0.125-inch larger ring-gear diameter and internal pinion support than the 12 bolt does. This is not much of a difference, but it is worth noting.

I recommend the Moser 9 inch, here is a link to my prices for the truetrac center and 31 spline axles. http://www.exoticperformanceplus.com....html?item=145 Bob

Yeah they are not cheap but when you get a good one you usually only have to do it once.

Yes it will work for your LT1. We are one of the largest retailers of Moser rears, check out my prices at this link. http://www.exoticperformanceplus.com....html?item=145 A Moser 9 inch is great for a daily driven car.

Thanks Darren, I appreciate it! Bob

What about the Dana rear ends? Less HP loss due to ring pinion angle like 12 bolt, and nearly indestructable. (All the big Hemi cars used 'em)
