PowerTrax Limited Slip Differential

Been reading where limited slip can make driving in slippery conditions hairy thru turns. I’m just looking for input from those that have an aftermarket LSD on these newer trucks with the light *** end.

uhm curious what you are reading about LSD's and slippery conditions. Every sports car I have driven in the last decade or more has had one or another version of LSD in it - aside from power madness - they are splendy in wet curvy conditions. Hell My DD is a 460RWHP sedan with LSD and I drove it this winter in 2 inches of snow. slowly of course but still I hadn't worry one about it.
in my F150 I have the open diff. I didn't opt for the elocker and I sort of want one but didn't really want to add all the other to get one package wise. I put 300 lbs of sand in the bed of that this winter and it helped significantly.

Limited slip diffs are open until torque is applied. So normal driving won't cause any slipping or sliding. If you plan to hit the gas in the middle of your turns in the rain then you might get the back end sliding IF you break both tires loose. Just don't do that.

Thats the info I was hoping to hear - still have much to learn. Thanks for your help.

Skyjockey, something like a Detroit locker has the ability to lock 100% or 0%. When you are turning the gears disengage and provide an open diff that allows smoothing turning. With a Detroit locker, if you apply to much throttle in a turn both wheels will get 50% available torque and there will be no more differential action (or very little), both tires turn the same speed, which is what can make vehicles with it break the rears loose in a turn. In a vehicle with something like a Torsen differential (Mustang), the LSD operates with friction using gears (or in a regular limited slip just clutch packs), and applies differential bias based on torque input and available traction at the wheels. These limited slips vary the torque available to each rear wheel based on available traction, and dont split evenly 50/50 like a Detroit locker, and thus dont have as much of an issue breaking tires loose on low traction surfaces like wet asphalt. They can actually give more torque to the wheel with more traction, and less to the lower traction wheel (inside wheel in a turn).

I found an eaton true trac for your 8.8 rear end. Go to stage 3 motorsports. Eaton says they don't make one for my year either, but they do and it will fit just fine. Many have put them in.

I cannot find it on the stage 3 Motorsports site. I sent them an email asking if they carry a TrueTrac to fit my truck.

talked to stage 3 motorsports - they do not have a TrueTrac for my truck. Looks like I will be going with the PowerTrax unit.
