I just got off the phone with Moser engineering and he reccomended a detroit/tractech locker to me. This is a helical gear locker instead of a clutch type, is this a good choice? Any other reccomendations? I will be running 31 splines. thanks!

I don't know why people freak out over detroit lockers. They are fine on the street you just have to know how to use it. They do ratchet a bit but it is no big deal. It is mostly dependant on how much gas you give it. Go easy around corners, and it will allow them to spin, if you lay into it they hook. Plus you won't have to worry about the discs wearing and your limited slip dying. Imagine having one wheel in a puddle of water and the other not and then laying into it, there goes your LSD.

Well, Ill tell you what I ordered (I am also doing a rear end rebuild/upgrade for my daily driver) I purchased the Detroit TrueTrac Differential (It seems very similar to the Torsen unit), a set of FRPP 4.10s, and Strange S/S 31 spline axles, along with all the install hardware.
my car is an 02 with a paxton 1000. My buddy had a jeep and said you need to be careful with those detroits because they will lock up on a turn or something. Whats this ratcheting your talking about? and this is a daily driven car that will see virtually no track time. 5-10 passes a year. But i will be running et streets or radials on the street. thanks again!

Ive used a detroit locker in daily driven Blazers/trucks for 6+ years without problems. You get used to them and learn how to drive with them. No biggie. If you gas it out of a turn they will lock and may chirp a tire and you'll have to turn a little sharper.
The Helical gear type locker is not a true locker or what most consider as a "detroit locker." The Helical gear one is the True Trac witch is a clutchless limited slip. Its better than a regular limited slip since there are no clutches to wear out. It wont be as "harsh" as a true locker. If I were to built a high HP car I would go locker. You can over power a limited slip and do one legged burnouts, the clutches wear, if its a real slippery road it can allow one wheel to spin, and they usually wont work right if turning.
Oh and the ratcheting is in the true "detroit ocker" or no spin. Its the sound of it dissengaging when coasting or going around turns. With any moderate to loud exhaust you wont hear anything. Except maybe a little tire chirp if you gas it doing a 90 degree turn from a stop. Just eas into the gas on turns and you'll be fine.

full lockers are a dangerous on wet,slippery,snowy surfaces..whatever. For off road use they are great. If and when I do my rear it will be the selectable type.

I drove a Blazer with a locker and mud tires (no siping for rain) in heavy rains. With gears and lots of power and didnt have any more problems than a vehicle with a good limited slip and street tires. If the driving conditions are bad then you drive accordinglly. Go easy on the throttle when its slick. Dont be afraid of lockers. Besides I would never drive my Mustang in snow.

This is from the info.pdf on the tractech website:
The Detroit Truetrac was the first gear type limited slip
differential in the industry. The patented design of parallel axis planetary helical gears provide a quiet, automatic splitting of torque. Power transfer goes literally unnoticed by the driver - even in front wheel drive axles.
The Detroit Truetrac performs like an open differential
under normal driving conditions and automatically
transfers torque to the wheel with better traction when
ground conditions warrant. The limited slip responds
instantly to torque feedback, anytime, at any speed.
