Torson differential

[splick]

Looking for some input on a torson differential in my Fury. Currently have an open differential and like the idea of a maintenance free unit. I had a torson in a high horsepower fwd car though and remember the severe torque steer. Does a rwd setup handle the torque loads better or am I better off just going with a plated differential?

That style of differential has been around since about 1963.

Maintenance on a clutched ltd slip differential is a non-issue, from my experience. Just use quality lube and the friction modifier additive to it.

On a rwd ltd slip axle, torque steer is not an issue on flat and level ground, paved or otherwise. Whereas torque steer on fwd cars can always be an issue. Allegedly, the more-equal the fwd axles are, the less torque steer results. More power, more possible torque steer, though.

Now, there are two types of "plated" ltd slip rear differentials. One is the prior style of "locked until it unlocks" (which HAS to have the friction modifier additive in the lube) and the "governor-weighted" style of "unlocked until it locks". The prior style can either have 4 individual tension springs or an S-shaped single tension spring. FEW of these will have complete lock-up, when "locked", though. Allegedly only about 75% lock-up. Whereas the "locker"-style will have complete lockup where one wheel will drive the vehicle forward with only ONE wheel touching "ground". Many GM dealer-training vids on this!

Just some thoughts and my experiences,

Thank you. I only have exp with the fwd setup and was concerned about if I would find the car being steered from the rear. About to build up a 383 for around 450-500 whp est. If that makes any difference. Going to be my long trip car so low maintenance and drivability are very important to me.

Thanks for the additional information. On the '77 Camaro I ordered new (with G80 PosiTraction rear axle), no long-term maintenance issues. Just fluid/additive changes every so often. Maybe I did it twice in 400K miles? At about 450K miles, rebuilt everything in the rear axle housing (except the PTrac unit) and it's still going at about 750K miles. LOTS of highway driving.

On the '69 Chevy pickup my Dad bought new, it did the normal pops and such on lh turns, with the factory PTrac and additive. Many changes to seek to lessen the pops, but finally got used to them. Just the way they were, back then, with PTracs. Kind of a status symbol to have a PTrac down here, back then.

Enjoy!

I don't think I want a very aggressive unit, more of an install and aside from fluid changes, forget about it. Thank you again for your perspective. I tend to go overboard the research and overthink things a bit. Not going to be a cheap build, but I really want the experience of touring the country in this car.
