well, we grenaded the 10bolt last night at the track. i dont know what to do now - a cheap 10bolt replacement as a temporary solution until my fund situation improves, or just bite the bullet, take out a(nother) loan, and buy an upgraded rear. so lets talk. i know i'm beating a dead horse, but i know JACK about rears.

i can get a complete 3.42 6sp rear for $250 and pay cash, not worry about a loan, and get an upgrade with my tax return in a few months.

i can just let the bastard sit until i get my tax return, then get an upgrade. i dont need the car, i can drive my truck.

i can run the $250 rear until it gives up the ghost, then get an upgrade.

or i can do the loan thing and buy an upgrade. i just would prefer not to take out another loan right now, honestly.



but if i do decide to go the upgrade route, what should i pick?? my car is making 420-430 to the tires (havent dynoed with the new intake yet), and i'd like to eventually (after the car is paid for) maybe add a bulletproof bottom end, and maybe eventually a turbo or 2. we only take the car to the track a few times a year, but i want something that will handle 5 grand launches on ET streets. i also want something that will still give me a lot of driveability - it's nothing for us to drive the car to florida 6 hours or something like that, or cruise in bumper-to-bumper traffic in myrtle beach, or just tool around town in it. so i want something street friendly that doesnt make too much racket, isnt clunky or clattery, and doesnt put too much strain on the driveline or tires. price isnt too much of an issue, i want the best and i'm willing to pay for it (up to a point). also, would these upgrades require new driveshafts? or new anything else?? and i'd of course like the keep the ABS and traction control, just for streetability and in case someone else would drive the car, for safety issues. of course i'm talking Dana 60, 12 bolt, and 9", and anything else there might be out there.

help me out guys, i know you're out there!!

 

also, teach me the stuff related to spool, differential, 4 channel, true-trac, detroit locker, all those terms are greek to me. and anything else you think i oughta know.

 

This is what I would do for now, that way you can still enjoy the car. Just don't go back to the track!!!
Once you have the money, buy a Moser 9 inch with 4.11 gears, and the Truetrac posi. $2,400.00 shipped. If you only have ABS, you have to disable it as Moser does not offer ABS with the nine inch. If you have traction control, then you're in luck as Moser does offer the 4 channel option for $100.00 extra. The Truetrac was made by Detroit, who made the Locker. Eaton recently bought them out. Bob

 

so what exactly are the truetrac and the locker?? what do they do?? like i said, i'm clueless. the only rear end i'm familiar with is the one attached to my backside, lol....

do any rear ends offer the ABS? what would driving the car be like without ABS?

 

DETROIT TRUETRAC TORQUE PROPORTIONING DIFFERENTIAL
The Detroit Truetrac is the first gear type limited slip differential in the industry. Its’ 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.

DETROIT LOCKERS
Moser Engineering carries a full line of Detroit Lockers to fit most popular rear ends used on the street, off-road, or on the racetrack. Detroit Lockers are fully automatic locking traction differentials, manufactured by Tractech, a well-known manufacturer of heavy-duty traction differentials for OEM and replacement applications. A Detroit Locker maximizes the available traction by delivering 100% of the torque and power to both drive wheels. It is engineered to keep both wheels in a constant drive mode, yet has the ability to unlock to permit the wheel to turn at different speeds if necessary.

Many people have had problems with the Locker, and I don't like the way they lock and unlock, as they tend to pull the back end of the car around. The Truetrac is what I recommend for all around useage.

Without ABS, if you slam hard to the brake pedal, the tires will lock up, just like they would on an older non ABS car. Personally, I don't like ABS, although it has made driving safer for those who cannot grasp threshold braking.

MOSER STEEL SPOOLS
Need to upgrade to a true performance spool? We carry a complete line of full spools for most race applications. By changing your carrier to a Moser performance spool, not only will you save weight, but you will also enhance the performance of your car. In addition to performing better, the life of your rear end will increase by reducing deflection in your case and eliminating the possibility of side gear failure. All Moser spools are heat-treated and precision machined. Moser spools are available for most popular rear ends including 10 & 12 bolts, 8.8” and 9” Ford, 8 ” Chrysler, and Dana 60. Moser spools are available in most popular spline counts and our steel spools carry a lifetime warranty to the original purchaser.

A spool locks both axles together all the time. With the rear you have in your car now, when you turn a sharp corner, the inside tire turns less revolutions than the outer tire. With a spool locking both tires together, the tires will tend to hop on sharp corners. Driving a spool on the roads for me is not a problem, as most of my driving is either rural or highway. Trying to parellel park with a spool would be pretty tough to do, so if you do a lot of city driving, a spool probably is not for you. Bob

 

come on folks... i know there's LOTS of people on here with aftermarket rear ends... or who at least know something about them, other than mr. epp here - given, i know he knows his stuff! but i'd like other input as well....

 

I say let it sit untill you get the tax return. Save the trouble and keep miles off the car. Almost winter anyways. If you are 100% going to upgrade it saves you from having to do the same work twice.

 

Just bite the bullet and get a mosar 9" 3.89 spool 33 spline axles and u will never have to worry again!!! And no the spool is not hard to drive u just got to know how to drive it! I have the exact setup but have 4.11 and hate them going to switch to 3.89 payed $1,900 from texas speed and performance.

 

I would wait until you get the money in cash for it. When you do decide to get a rear end though. Go with a Moser 9" with 3:89 or 4:11 gears, 31 Spline axles, and the true-trac. Oh and order it from either Scott at DLS or Bob at EPP.

 

thanks for the info, and any more out there would also be appreciated. really appreciated the locker/spool/etc info from mr. epp.
