Differentials...which would you recommend?
I am looking for your advice on which diff to go with. I am not sure whickh would be my best choice.
I do not drive it daily and I like racing it. I drive to Cayuga and Grand Bend from London area so it does get miles put on it going to the races. Just mentioning this as it may influence the advice you give. I also will be running slicks and yes I will be using 31 spline Moser or Strange axles. The write ups are taking right off the steeda.ca website as this is where I will be purchasing my axels and differential from. I have been running the car with 28 spline Moser Axles and I think as I want to go to slicks that I should upgrade. Thanks
Eaton Posi Differential
The newest technology in performance differentials comes from one of the oldest names in the business, “Eaton Posi”. This hot new differential uses high tech carbon fiber clutch packs to limit wheel spin and improve durability.
We also have this one to choose from.
Auburn Locking Differentials
Tired of spinning your wheels instead of winning races? Stop the “One Wheel Peel” with Auburn’s heavy-duty locking differentials. Auburn differentials use cone-type clutches instead of plates. This proven design means excellent performance on the track, and great drivability on the street. Auburn Lockers are available for 28 or 31 spline axles.
and this one..
"Tru Trac" Tractech Differentials
Go beyond clutch type limited slip differentials. Trac-tech’s differentials have no clutches to wear out. These are the differentials we use in our endurance race cars, including the famous #20 Car. “Tru Trac” differentials use a “torque sensing” worm and scroll gear mechanism to smoothly transfer power to the wheel with the most traction without chatter or noise.
I did a search for the company Tractech and it always directs me to the Eaton page, so me thinks Eaton bought them.
and lastly...
"Detroit Locker" Tractech Differentials
Go beyond clutch type limited slip differentials. Trac-tech’s differentials have no clutches to wear out. These are the differentials we use in our endurance race cars, including the famous #20 Car. The “Detroit Locker” is a positive action ratchet type differential that lets the outside wheel turn faster in corners and locks up like a spool if a wheel starts to spin. “Detroit Lockers” are recommended for offroad racing use only due to their decisive (and noisy) ratchet engagement.
Comments please. thanks

Well in my ride I went with a 8.8" rear with 4:10 gears and a full spool. I welded the axel tubes and installed c-clip eliminators and a MAC rearend girdle. I launch my car at 6200rpm and have had no problem at all. Just my opinion. :biggrin:

Greg, I got a FRPP Trac-Lok 31 spline diff waiting to go in... along with strange axles and a frpp axle girlde (same as yours, just FRPP branded). From what I read up on, this was the best combo for something that is driven and taken down the strip. Just my opinion, I'm sure someone else will disagree

No problem.. also check the issue of Modified Mustangs on the stands now.. they have a product overview of a few different diffs (eaton, auburn) and some axles.. not much info.. but if you already have it check it out

Three that I recommend
Eaton- Strongest non locking Diff.
Detroit Locker- Bullet Proof but noisy/jerky
FRPP 31 spline- This is what I run, cheap and strong. 6000 RPM Launches on slicks. Some have run 9's on these diffs.
In either cases, get a good diff girdle, control arms and eliminate wheelhop.

If all you do is drive it to those tracks, and occassionally around town I'd get a full spool, cheapest, easiest, and best piece for stright line performance (as far as rears for). When I upgrade mine it's a toss up between the FRPP 31 spline carrier, and f150 carrier, or a spool. I'm prolly going to go with the spool though.
