Aftermarket Diff Locks

[pmatusov]

For general and expedition use (not rock crawling) I would recommend Torsen-type differential locks. Benefits:

I beg to differ. My D1 with two TruTracs did fine on the Rubicon. I drove it on snow and ice, including off-camber mountain roads - it did okay.

Which code reader do you use? I have found that the gas tank meter is very sensitive, and I would love to reset that on my own. Thanks

An old cheap one that I have had for a while. Nothing fancy at all but it works.

While on a group trail ride last week, one of the Grenadiers refused to allow diff locks. It turns out that the owner overfilled his fuel tank and that threw a check engine light. The computer won't allow for use of the lockers if a check engine light is on. Fortunately, I carry my code reader and was able to reset his check engine and then lockers were allowed.

How stupid is it to not allow lockers because of a check engine light! Great way to get someone stuck in a remote place of what might be an emissions sensor or something else minor. This makes me even more motivated to find a backup way to activate diff locks.

This would be the perfect truck if not for the stupid software.

I thought I’ve used my lockers with check engine light, but I’ll be sure to test it the next time it pops on from due level sensor. I get it every couple months. I have a $20 obd2 code reader from Amazon so I can erase it myself in the car because I know it also disables cruise control.

TruTrac and Torsen both are LSD. They you different tech to accomplish the same thing. Both are very good. I LSD on an old CJ and it never lacked for traction while still being very drivable on the road. No need to push button off road. Their down side might be ultimate life expectancy but still a very go option and one I would be happy with on most trucks.

There are no slipping discs in my torsen differentials, as far as I have seen?

Thanks, I am well aware
Ultimate life expectancy - the rear TruTrac lived in my Disco for 220 thousand miles, the front - 120. Both were fine when I sold the truck with 290kmi, though the rear was a little looser than the front.
Their efficiency is limited by the ratio of the tire rolling radius to the mean radius of the brake pads.

Along with a hitch, these should NEVER be built with out lockers. HUGE mistake

Just for thought here.....
Toyotas , Ford Broncos, Jeeps, they all have locker and non-locker options. I wanted a Grenadier, and I did not want to pay extra for a model with lockers. 70K out the door was my max (my wife is still mad at me for paying $70).
I have had a 4X4 Tacoma (2017), Tundra (2018)., 3 FJs 2007,2008,2014), and a Bronco (2022) none with front and rear lockers, and never needed them in my 40 years of ownership. Lots of folks don't rock crawl (I don't want to damage my $70K truck. I also own an AWD Ford Van and a Subaru AWD, they fit my needs perfectly!

He may be implying a few things. 1) Ineos traction control isn’t up to par 2) if you’re not headed places with this that may need a locker, you’re not in the ideal rig for the job 3) 1 and 2 generally make a lockerless Gren worth shit resale so the investment up front may be worth it.

Looking at some of the other groups and what new products and solutions companies have developed for the Grenadier I would be pretty confident there will be an aftermarket difflock solution in development and available in the near future.

I don’t understand what you’re seeing.

I don’t understand what you’re seeing.

Every now and then there are interesting images of components and technical titbits that are not from Ineos. Upfitters don't just disassemble components from new cars for no reason or to settle their curiosity, generally there is more going on in the back ground that that is not directly mentioned.

He is seeing the fast fashion of roof racks, wheels and drawer systems etc that are flooding the market. Seems like everyone is rushing to get a piece of the Grenadier market. What many don't get is that much of this stuff is either cheap to churn out with basically zero development or are parts that are effectively generic and being half ass adapted to fit the Grenadier. The evolution of steering stabilizers for the Grenadier is a prime example of that.
But lockers are a different animal. They have to be precisely fitted to the axle and you can't just add a couple washers here and there to make it work. That said, if ARB happens to have a blank that is close then they may produce something at some point. There is a good chance that a Dana 44 or even a rover blank may be able to be machined to match the Cararro axles. But Ineos needs to pick up sales for that to happen and those sales better be locker less trucks. This is where things may get tough. Land rovers didn't come from the factory with lockers, so the demand was high. But I bet 3/4 of all grenadiers have lockers. That waters down the available pool of customers for an aftermarket locker. And those locker less trucks will likely have to go through at least one owner to depreciate the vehicle enough to make it worth it and to get an owner not scared of scratching their $70k plus truck. So, again Ineos better sell a crap ton of locker less trucks for this to happen.

Does an aftermarket diff lock make any sense? The original difflocks seem to be pretty much integrated with the overall system, aren't they?

Grenadier? Purchase? Get lockers.

Bingo. Unless someone thinks the gren locker market bears a 200% premium over typical unit prices in the future, I don’t see anyone making a good business case for the R&D.
