The cars is a 2002 Camaro with TH400 and a 450+ HP motor with a 200-300 shot on it. Should I get a Spooled 12bolt or 9". I would like to get a 12-bolt because they are lighter but I'm afraid that it would be too weak what would you guys do?

 

Strange Dana S60 is my recommendation. Strong as an Ox.

 

Moser 9 inch with a spool. Bob

 

ive got a 12bolt put in about 2+ years ago but if the s60 was available back then i would have gotten it. you cant get anything stronger and its cheaper than the 12bolt and 9".

 

The 68 had well over 200 transbrake launches on its old Dana 60. 3400 lb always kitted to well over 1000 RWHP with a Supercharged N2O combo. Followed by another 100 plus passes with a 540 N2O motor at 900+ RWHP No appreciable wear other than the stock posi failing early in its life, which was replaced with a spool. My other cars have had similar power levels, with both 9" and 12 bolts- no failures. Pick your poisen. unless something is wrong with the latest products from the after market (other than gear set up, maybe?) Any of the rear ends you suggested should fullfill your requirements. By the bye; I have a newly installed Moser 12 bolt in my TT Iroc and will definatly check the set up before running due to all of the hoopla over gear noise in the after market rear ends.

 

Moser 9'' here, 4.30:1 with 35 splines, Detroit Locker in a M6 car and i'm very satisfied except that the Locker is a little rough for street use and DD (It clunks a lot in parking lot but traction is great). On the other hand, when I go to the track, I don't have to worry about breaking side gears or gear whine like 12-bolt guys (6500 rpm clutch dump with 28x10.5 MT slicks). It's heavy but just ad more horsepower and forget about it. If you buy a 12-bolt, just get a spool because posi units are the weak point.

For a car with a th400 you don't need more than a 12 bolt. I got several friends runnin 9's-10's with em and a 12 bolt.

 

Thanks for your help guys! Anyone have a Billingsley Fabbed 9" in their car?

 

to the top

 

Thats what I'm going with when my 10 bolt takes a **** on me.

 

I voted Strange 9".....I plan on getting this rear....Looks to be unbreakable

 

I don't believe Strange offers a 9' housing for the f bod.

 

WHAT....They don't.??????

 

I know Moser does. I've never seen a Strange 9 inch. Who seels one?

 

probably STRANGE.

 

Well I don't see it in their online catalogue, GMHP ads, nor do any of the sponsors (Strange dealers) sell em.

 

I can get you a Moser 9 inch headed your way in two days. Bob
