KevH Posted June 5, 2017 Share Posted June 5, 2017 Why is limited slip no longer an option on the 2015+ trucks? Quote Link to comment Share on other sites More sharing options...

MY93SHO Posted June 5, 2017 Share Posted June 5, 2017 (edited) I just built one online, have to have 3.73 gears for limited slip EDIT: I was wrong, 3.55 limited slip is offered also Edited June 5, 2017 by MY93SHO Quote Link to comment Share on other sites More sharing options...

Don't know about Ram but GM has been electronic for a while now too. They're kind of "limited locking" at low speeds only.

akirby Posted June 5, 2017 Share Posted June 5, 2017 They're kind of "limited locking" at low speeds only. I didn't think they were necessarily speed limited - just not for use on dry pavement. But if you think about it - the only time you really need it is in slippery conditions to begin with, so if you're slipping lock it and it works the same way. 1 Quote Link to comment Share on other sites More sharing options...
spotdog14 Posted June 5, 2017 Share Posted June 5, 2017 They have switched to e-lockers. I've got one in our 2015 F-150 and like it so far. Quote Link to comment Share on other sites More sharing options...

Speed limited as in they don't activate at 75mph going down I-90. According to this we're both right. "The electronic locking differential is a device housed in the rear axle that allows both rear wheels to turn at the same speed. The electronic locking differential can provide additional traction should your vehicle become stuck. You can activate the differential electronically and shift it on the fly within the differential operating speed range. The differential is for use in mud, rocks, sand, or any off-road condition where you need maximum traction. It is not for use on dry pavement."

akirby Posted June 5, 2017 Share Posted June 5, 2017 According to the manual it works up to 55 mph. I just meant that it wasn't limited only to very slow speeds. 55 is pretty fast for off-road/slippery conditions. Quote Link to comment Share on other sites More sharing options...
KevH Posted June 6, 2017 Author Share Posted June 6, 2017 Do you think someone will make a mechanical limited slip for these trucks? I sent an e-mail to Eaton about the Truetrac and they said there is nothing in development. Quote Link to comment Share on other sites More sharing options...
