Rear E locker options

[Eaglehemi345]

my 2020 ram 1500 sport. it does not have a rear diff lock from the factory. want to add one but don't know what my options are. Anyone did that before?

It should be doable. However, I think they only work on 3.92 gears. You'll probably need to talk to Ram to see.

I have elocker on my 3.21's from factory.

Oh cool. Should be completely doable then.

You can get aftermarket kits too if the stock option is expensive. It will require a new button and possibly some programming to activate it. I personally I would do an anti slip / limited slip rear unless you plan on rock crawling. It will activate on its own... my only complaint is that on wet roads it can get squirrelly. I keep the auto 4wd on and that resolves it for me.

Already have the lsd in the truck from factory. Also 3.92 gearing. I would definitely need an aux switch. factory auto 4wd button will be useless.

Ram 1500 Rear Electric Diff Locker - 2011 to 2023 - LTG4x4

Did some research. There are very few aftermarket options available for these trucks. The only other option is an ARB 259 air locker or OEM lock from mopar.

The problem with the newer anti-spin diff is that there is no pre-load on them. They act like an open differential until enough torque differential is applied then they lock up basically like an autolocking rear. My old truck was a 2002 ram and had the old style limited slip which was better because the wheels were locked together until enough toque caused them to separate. Eaton makes a suretrac pre-loaded limited slip that would be cheaper than an e-locker and they are pretty much bullet proof. Just a thought.

I had a local shop quote me around $1,500 installed for the eaton suretrac installed for another truck I was looking at.

Suretrac is LSD.

Correct.

The carrier for 3.21 and 3.92 is the same.. a regular 9.25 Chrysler carrier will fit. But you'd need the right bolt pattern drilled in the carrier if reusing stock ring gear. Otherwise youd need a regular 9.25 gear set

Glad I found this thread as I was about to post one similar so (not highjacking) hopefully expanding on the +/- of each
My e-locker 3.92 4x4 has traction problems. When I bought it a few months ago I noticed the RR tire was noticeably thinner than the rest? I have since pimped it out for ME so 35x12.5 BFG's wheels...blah blah...BUT I too find myself spinning the RR tire frequently.
So is my e-locker an OPEN UNTIL i engage it? (which sux because it disengages at 20 mph)
Is there a "true posi" (clutch type) offered on these trucks (i would greatly prefer)
Is the "anit-spin" diff like the older GM GOV-LOK (after 1 wheel makes 3 revolutions more than the other it locks together)?

 

[H2OMAN]

I haven't had lsd since my 2012 so I can't answer that on the Gen 5. But the diff on your elocker is open until engaged.

Nope, it applies pressure to the clutches only under acceleration, kinda useless IMO.
My `72 AMX had a true limited slip diff. that thing was a hoot in the rain.

Yes the new generation anti spin diffs are not actually limited slip because they are not pre-loaded and act like an open differential until enough torque difference causes them to lock (my guess is they did this for fuel economy), so yes it's more like the GM locking diff but still acts different because it's still a clutch pack not an actual locker so they still do slip some. I think the owners manual even says you may have to apply the brake slightly to get it lock up if one wheel is spinning and the other one isn't. Who is going to remember to do that when you're spinning on snow or in the mud right? My old truck, 2002 was a true limited slip because both wheels turned the same until enough torque caused one of them to slip (it uses a spring loaded clutch pack to lock both axles and slips when enough torque brakes the clutches loose. And yes the e-locker which is what I have now is a true open differential until you lock it and yes it unlocks at 20 mph and then re-locks if you slow down below 20 again. If you want a true old fashion style limited slip diff I believe you would have to go aftermarket, like I said earlier Eaton suretrac is the way to go for true limited slip.
Sorry

I agree my 2002 ram was a handful in the rain when it would brake loose, instant fishtail
