Want my Roadmaster to spin em' both under WOT... any ideas? I have a 1995 Roadmaster that currently has an open diff with a 2.97 ratio. I want to upgrade to 3:73's and some type of posi traction.
What would you guys recommend if you were in my situation? Detroit Locker? A Posi unit? What brands? What would I be looking at cost wise?
This is for the 95 Buick Roadmaster, which shared the platform with the 94-96 Impala SS, Caprice, and Fleetwood. I believe they had 8.8 rear ends.

Are u sure you don't mean 8.5 inch 10 bolt? I though the 8.8 was all Ford. I could be wrong since I haven't researched this.
I'm surprised you can't spin the tires unless you got the 'one wheel wonder' going on. U need to find out what diff you got. I figured your car would at least have a limited slip like us f-bodys. I've always ran the stock diff without any problems, there's no way I'm spending that kind of money for Det locker or other posi unit.

Grab a 3.42 rear end out of an M6 car - you'll like the gears, and the pair of marks it'll leave behind you. Toss in a converter and a shift kit and you'll be in a whole new world.

Yea, the factory Auburn units suck and don't last more than about 80k miles before they burn out. I used an Eaton and love it, toss in some lower gears and play.

A Roadmaster got the 8.5" axle and 2.93 was the good gearing, some came with 2.56s.
The 8.5" axle was standard on LT1 powered b-bodies which means the only 94-6 b-bodies that could have gotten a 7.5" are the L99 Caprice sedans and of those only the civilian cars got the 7.5" the police ones got 8.5".
I would look at either a TruTrac or a Torsen, the Eaton wears out too quickly and rebuilding it cost almost new, those are geared posis not clutch so they should not wear out.
I have had 3.42s and 3.73s in my car, the 3.42s were a little nicer on long trips but the 3.73s were fine for that even and obviously better from a stop.

What are the "G" codes in the SPID?
The b-body makes for an interesting hotrod platform. Yeah you have weight to deal with but you also have a full frame and suspension that needs just LCAs and an airlift bag to hook hard at the track. Not to mention it is more comfortable than most other cars guys modify.

Buffman is debating selling his modded Roadmaster, I can provide a link if anyone wants it. Here is a pic of a Roady doing burnout though.

I think he's just talking about an Eaton wearing out quicker vs. a conventional gear driven posi, which I couldn't agree more. This is one heavy sucker and I really think it's screaming for a locker.
