I can't imagine wanting any car that didn't have a posi, or Limited Slip Differential, for the more sophisticated and refined Mopar drivers out there...
After reading more info on other sites, I will probably get one for my next build. Some info here is good, after weeding through the humor. Would there be a minimum or maximum gear ratio for a daily driver? I currently have 3:73. Maybe a 3:52? I'm not really concerned with MPG, just off the line acceleration.
I had a 3.08 posi with a 350hp 350 in The Roach Rod... with a four speed. You could dump the clutch at 5000rpm and roast the tires. To me... that's what hot roddin gis all about. Watch the video from 1:20min and see for yourself... <iframe width="420" height="315" src="http://www.youtube.com/embed/hcRfvUGL67k" frameborder="0" allowfullscreen></iframe> Sam
I think those of us up here in the north country probably have a "leg up" due to snow and ice. It gets to be a long winter if you don't know how to drive in slippery conditions and high power to weight ratio is just slippery conditions!
I just installed a 8.8 explorer rear end w/3.73 limited slip and have not had any problems but i dont drive in the rain
Do the "posi" rear ends that you find in an S-10 truck lock in and out only when it senses one wheel spining or are both wheels locked all the time? The only reason I asked about these is I was told the S-10 is a good rear for T's as opposed to a 9 inch because the 9 inch has an offset pinion or center or something like that? Then another thing I read said the 66-77 Bronco 9 inch rears were center pinion and were good for T buckets. I just figured take the path of least resistance and get one out of an S-10 if they work because they seem to be everywhere.
Pretty much all rear ends that are commom to what we install them in have the pinions midpoint of the housings and the ring gear is offset, except the front diff's on a four wheel drives. If you want the rear cover centered then one must cut the axle tubes and rework the axles and run the drive shaft at an angle.
S10s came with several different rear axles that were all ten bolts The S10 came with a 7.5, 7 5/8, 8.5, or an 8.6. S10 crewcabs with the 7 5/8 axle and S10s with the 8.6 came with rear disk brakes. No matter which axle you got, there were only two variations, open or the G80 code gov' lock by eaton. The way these work is that the wheel with the least amount of traction gets the most torque until the the rpm difference between the axles is great enough to flip the lock out. It's a Cheasy rinkydink little dealy that wears out. That's all you can get from the factory. You can instal a locker as easy as changing the spider gears. Or get a different carrier
If you want off-the-line acceleration, go with lower (numerically higher) gears. The 3.73 is a great all-around performer.
