Thoughts on Detroit TruTrac?

[EcoJuice22]

Hey all,

So I found out that eaton is offering a Detroit TruTrac and an E-locker for Broncos.

It looks like this is targeted at units with the open diff and 3.73 gears.

I decided to call Eaton and ask about how the LSD would work with Trail Turn Assist and they said they haven't encountered any issues on their test units. I'm not entirely convinced, since I feel like this would put added strain on the drive train when the vehicle has to overcome the resistance of the LSD.

Anyone have any thoughts or opinions on this ?

Just my thoughts here..... The Eaton TrueTrac does still allow slipping. It can only do a 3:1 torque transfer. The Trail Turn Assist uses the brakes to hold the inside wheel stationary. The brakes can overcome the torque transfer from the TrueTrac and you will still see the outside tire spin.
Something like an ARB air locker would be a totally different story.

Trail Turn Assist uses the brakes to actuate so it shouldn't matter.

I agree. It should work just fine. The Truetrac is a great option for those that do not need a locker.

I get that trail turn assist uses brake actuation to work.

I was just thinking there's gotta be more strain put on the transfer case and driveshaft.

Nonetheless, I'm thinking it's a good option for my vehicle since I don't do crazy off roading and I think it would help a lot in the winter when I like to stay in 2wd. I think it's a great price point for improving slippery conditions

Last time I used a Detroit TruTrac was around 2002, but in general they are a great upgrade option over lets say OEM spyder gears and clutches.

Ford thinks it is OK, since they do it on F150 Raptor with front LSD.

Do you have any feedback, did you install the LSD?

Best,

I have Torsen differentials (front and rear) on my 02 Ranger. They are basically the same thing as the Detroit TrueTrac. I also have a TrueTrac on my 69 Cobra. I see no reason why there would be any issue with Trail Turn Assist with a TrueTrac rear differential. Having the TrueTrac on the front may hinder it a bit but that is just a guess.

Neither TrueTrac or Torsen lock but act kind of like a locker when accelerating. I don't see Trail Turn Assist replicating acceleration.

Trail turn assist locks one rear wheel with the brake forcing all torque and double speed to the opposite wheel…not possible with a “locker” and not a good idea with a limited slip either…much less a problem in the front axle (I may even lock the front on loose surfaces using TTA)…

Before I got my rear locker I have to admit I thought long and hard about a True-Trac.

Still am for the front axle to be honest. If the open diff non-locker rear end didn't have the F'n welded gear... and If the m210 didn't come with an e-locker already installed, I probably would on the front even with a rear locker. But I don't think I'd rip out a functional e-locker for a LSD.

LSD isn't as good as a locker when you really really need it, but it's also always on and you don't have the risk of screwing up by turning it on in the wrong spot...

My BRZ has a torsen rear diff and it functions very well, great for street driving. E-lockers can be useful mainly for certain off-road situations, but have jumped the shark in terms of how many vehicles are getting equiped with them. They are useless for most owners on pavement and a limited slip would have been a better option.

A Sas appearance package would have been the better way to go for most customers, with e-lockers a separate option for buyers who legit have a use for them.

if it wasnt for the deep sand and occasional road flooding at my new house i would still have my 86 instead of the bronco. I was weeks away from installing a lift kit and geolanders then a wildtrak at MSRP showed up right before I was submitting an order.

that being said, I wouldn’t put Torsen on a Bronco rear end.
