Default Torsen style diff/LSD

I asked this question in another thread, but maybe it should have its own thread. I am wondering where this info comes from. I have read it in a few threads. Being excited that we didn't have the clutch pack lsd that wears out, I wanted to read about the new LSD but I cant find an ounce of official info about ram using this in the 1500's. Does anyone have some info about this? I would have thought that ram would be bragging this up and info would be easier to find.

You'd be surprised how many people are clueless about differentials. I test drove a 2014 Silverado at the Texas State Fair, and asked the Chevy rep who was riding with me what the diff ratio was in the truck. Not only did he not know, he didn't know what ratios were available. In fact all he could tell me about it was that it had an auto e-locker (which is badass by the way). Most of my friends have no idea what type of diff their trucks have either.

Anyway, to answer your question here is a link to an article on Allpar that talks about the LSDs. Its in the axles section in the last paragraph.

I was also excited to find that they went away from clutch pack LSDs in the 2013s since my truck has the 3.21 LSD rear. In my opinion clutch pack LSDs are more trouble than they're worth.

Everything you could ever want to know about the limited slip axles in todays RAM's:

The purpose of the Limited Slip Differential is to provide a torque bias within the differential allowing torque to be transmitted to the high traction tire in a variety of traction situations. The Limited Slip Differential is a torque sensing device and is not dependent on vehicle speed. Using the vehicle traction control system in combination with the Limited Slip Differential enhances the vehicles traction capability. The Limited Slip Differential is a non-preload design, this provides optimal fuel efficiency while still maintaining improved traction performance. The Limited Slip Differential operates as a torque sensing device because when torque is applied to the differential gear set the reaction forces of the bevel gears apply an axial force into the clutch system providing the torque bias. When the input torque is very low the reaction forces will decrease allowing the differential to act similar to an open differential (zero preload). Under normal operation the differential gears can be turned by hand.


They should really put this crap in the owners manual.
