Thread: Posi Suggestions?????

Tweet

Hi Guys,

I need a suggestion for a locking differential for street use in a Ford 8" rearend.

Thanks

DO NOT BUY A LOCKER. buy an eaton, or moroso if your planning on putting out 500 horse or so.

Does anyone have any experience with Powertrax?

That is the locker im talking about, i should have cleared that up earlier, powertrax, my friend bought one, its horrible, he wasted about 350 bucks and ended up pulling it out and welding the spidergears, works better than that did. If you really want one i bet he will deal on it haha.

Get yourself a limited slip positraction carrier.
An 'Auburn' posi is a good one. A 'cone style' that gives good grip without too much trouble. Same with a disc type clutch pack. Only things you need to watch are (a) posi lube addative is required, and having your tire size (rollout) match is real important.
Stay away from 'locker' type units on the street. They are fine when they are in 'lockup' as long as you are going straight...But if you go around a corner and it is wet...they may not unlock and you may spin the bugger out... Or...You have to spin the tires to get the locker part to latch in. If you don't, then if you take off at, say, 3/4 throttle and get on it without spinning the tires...it will drive off of one wheel. Feels a bit squirrely then..dart one way on the gas, and the other way when you back out of it...
I had a Detroit locker (9") in my truck and replaced it with an Auburn posi.. Smooth as silk with the Auburn. Clunky and jerky with the locker...
Hope the info helps...

My wife`s car has a Benson (yes John SR., Johnny`s dad) quick change w/ spool. Sure does seem to feed both wheels real good. Corners are a totally different matter alltogether. CORDially J.B.

Hey Jeff, Is that a Studebaker Coupe Express?? Have one that does double-duty towing my 32 Auburn V-12 Boat tail and my Hacker-Craft triple cockpit drake back W/ a Liberty V-12. Cool trucks. CORDially Jerry
