moser 9 inch rear
hey guys i was interested in buying a 3000 dollar moser 9 inch from hawks thirdgen... this is what i wanted to get
http://www.hawksthirdgenparts.com/ca...wposiunit.aspx
which would be better for street driving the detriot locker or the tru-track... either way i wanted to get it with 31 splines and 3.50 gears.. also i wanted to know how much better is this than the ls1 rear end... im asking because this will be behind a fairly strong engine and i dont wont to worry about shredding teeth or screwing up the rear end like i did my stock nine bolt and lt1 rear...
355 vortec block
FIRST TPI intake
afr 180 heads
gm hotcam
2800 vigilante stall
dana probuilt automatic

Re: moser 9 inch rear
way overpriced IMO. hop on ls1tech and there are several vendors selling them cheaper.
Why 3.50 gears though? A deeper gear would result in better ET and quicker 60'. Also now is the time to upgrade to that aluminum center if you want, the detroit locker is no where near as streetable as the tru trac. Just remember if you want the tru trac to live, you have to hit it immediately and hard in the burnout box or you'll break it under power if it doesn't lock up both wheels. A detroit locker is very clunky while driving, especially around turns and it doesn't engage or disengage both axles at the same time, so you'll feel it push the car left or right since one axle will be under power before the other. The rear end is much much beefier than a 10/9 bolt. You shouldn't have any issues with it at all.

Re: moser 9 inch rear
Wavetrac is what i want to go with but they are $$$. I heard good things about them.
I highly doubt your setup will cause harm to a big 9" tru trac system tho. I couldnt break my LS1 10 bolts with a hotter combo. You should be fine

well im still running tpi and i heard that 3.42s were the limit for tpi... but then again i dont drag race and i do like the get up and go so 3.75 gears might be good.... im not even concerned with top speed im more for acceleration up to about 85mph and thats it for me...
also when you mean hit it hard and do burnouts do you mean only do that once i get it in the car... im confused... do you have to break it in or something...

Re: moser 9 inch rear
lol how you think i feel? This rear should have broke along time ago and it hasnt yet I did break my 9 bolt on a stock motor.
But like said, its peace of mind...other vendors are selling them for MUCH cheaper depending on what you get. i'd browse around. I know spohn sells them for few hundreds less.

Re: moser 9 inch rear
Hmm, I never had issues with my 9 bolt... even with my drag radials. I wouldn't worry about setting up to a 9 inch just yet, but it is all up to you. I think I am going to be looking to build an 8.8 for mine.

Re: moser 9 inch rear
yeah i know what you guys are saying... if it aint broke dont fix it lol.... maybe the girdle would make feel better lol.... is it normal for the rears to make a whistling noise from 60-66mph... this one does that at those mphs, but as soon as you let off the gas its quiet... the rear is smooth and quiet and i like that about it...

Re: moser 9 inch rear
Detroit locker All the way.
I dont know what all the HUBBUB is about not any fun on the street!/streetable.
set up the right way. thay are Pussycats!
1. they Make NO SOUND at all. in my car they do NOT!
and i have 4.11 gears and south side bars.. if it made any sound you Would know it!
2. unlike A clutch Type posi. you dont need anything but Good gear Lube.
nothing more.
3. you will always turn 2 rear tires over when doing a burn out!
(unless going into a turn) then it has a push on the drive wheel till you get almost stright. then the other wheel kicks in.. if you go into a drift mode then both stay locked. (ask me how i know!)
NEVER CLUNCKY AT ANY TIME! get one set up right and new. you will Love it!
mine came in all set up from Currie entrs. with 4.11 's100% Bolt in took just me 45 min to install!
LOCKER ALL THE WAY!! YOU WILL never look Back!
before i raced chevys. i was a ford Guy! love My Lockers. the one i had before this was set up with 4.86 and 30" tall tires. 67 ford Fairlane GTA 390+CID.. Miss her (1983/1989)
i had 3 lockers for that car 4.11/4.56/4.86.
and my Z28 now also has a locker..all smooth has glass. (just me?)

Re: moser 9 inch rear
I have a locker in mine, it does make clangs bangs and all kinds of noises. I have rod ended control arms on my moser 9" and its very loud in the car.
They do push funny when you accel and deccel in corners.
I was wanting to put in a tru-trac but Im reading weird things about them so I havent yet. Sounds like some are working right an some aren't. I may just move to a spool and b done with it.

Re: moser 9 inch rear
I would get it looked at. by someone who knows lockers.
should be smooth at all times. just that funny push this in a turn.
my first time with lockes was from a guy who worked for Ford.
doing rear ends. he set all mine 3rd members up with lockers.
this locker i have now is the same has my other lockers.
new in box then installed by a compy who is well known.
for there 9" rear ends.

Re: moser 9 inch rear
lmao....if it DOESN'T clunk and bang around turns then it's NOT working right. Under any form of power they will be locked up, so that's foot off the gas going around a turn or it'll lock up and you might as well have a spool.
every detroit locker I've ever been around from mud trucks to sand dunes trucks, to race cars, etc etc ALL bang. It's the nature of the beast you are going to hear it ratchet around a turn, if you're not hearing anything, then maybe you don't have one.

Re: moser 9 inch rear
Yup, everyone I have ever drove or rode in has made noise. All of them were new out of the box. except the 2 from a 1970 429 SCJ torino.. they make the same noises...
Lockers arent smooth and thats what made them strong at the strip. I have heard of softer springs for them for road racing buut I dont know if thats true or not..

Re: moser 9 inch rear
sheesh, i thought that there were no complaints as far as aftermarket rear ends go.... you would think that spending that much money on a rear end would have NO problems or concerns... i dont want a rear end that clunks and bangs around corners or turns even if it is normal and i dont want the whining noise that alot of people say with aftermarket rears also.. now it kinda makes me feel like i dont wanna spend a pretty penny on a rear and have clunking and whining noises lol.... my ls1 rear end doesnt give me near the headache and its pretty quiet...

I don't mind the locker and you may not either but its nice to have a bit of warning about what to expect..

Re: moser 9 inch rear
I honestly think you will never hurt a 9" tru-track with your combination....I've seen way too many 10 bolts live behind similar combos or even more aggressive combinations to even worry about a 9" failing. 
Get whatever you like. Auburn even makes a posi for a 9". Or you can go Eaton with a 12 bolt and be just as good. Any of those should work fine

Re: moser 9 inch rear
I've got a Detroit Locker in mine and I like it. I dont hear any noises from mine while driving, but my exhaust is loud. If I have to push the car, I do hear it ratcheting around turns. When going around turns, just stay off the gas and its nice and smooth. If you stay on the gas lightly, you will feel the rear kinda hop around the turn since both wheels are locked.
I'm glad some of you mentioned about the funny sideways push when accelerating. I've been trying to figure out for a while now what that was.
