Post Detroit Locker vs. Lockright

Could someone tell me what the advantages are of a Detroit Locker (not an EZ locker) over a Lockright? Is it a strength issue, or what? If so, anyone have trouble with lockrights?

Assuming you are talking about a Toy 8"Diff. I have ran a lockright for about 3 years. It's ok and has done everything I have expected of it. I get on it pretty hard sometimes too. Strength wise, the Detroit is definetly stronger and you would probably never break it. Lockrights OTOH could fail ie: little pins fail, stripped or broken teeth, even broken cross pin. If you have the money and are going to run a Toy axle for a long time, get a detroit. If your on a budget, need a locker, and don't hardcore wheel everyday, get the LR. JMO!! I don't think you'll notice much difference between the 2 on the street, the LR will probably be easier to hear though click-click-click-click-boom! <IMG SRC="smilies/biggrin.gif" border="0">

Once my soft locker broke in, I hardly notice it at all. The on road driving is beautiful. If U can afford it, get the detroit.

You can buy two LR's for the price of one Detroit, LR's work well for every person I know and the price is right..

The added carier strength is practically a non-issue with Toyota 8" diff's...

I think it would be downright foolish to spend $450 on a Detroit to just lock the rear when for a few bucks you can be locked front AND rear...

I run a lockright in the rear and never had a single problem out of it <IMG SRC="smilies/smile.gif" border="0">

Maybe, but any slop or wear in a worn diff will be audible and likely lead to failure with a LR.

This still doesn't even address the risk of a LR failure as mentioned above. I know DRM has never had a problem <IMG SRC="smilies/rolleyes.gif" border="0">, but that doesn't exactly mean no-one else never has.

If you spec out the carrier before the install (like the directions tel you to), there is no reason for failure of the lockright doe to "slop". And to be honest, I don;t see that "audible" has to do with this?

This still doesn't even address the risk of a LR failure as mentioned above. I know DRM has never had a problem <IMG SRC="smilies/rolleyes.gif" border="0">, but that doesn't exactly mean no-one else never has.

"risk of failure"? There is a risk of failure from ANYTHING...

I would like to hear from anyone who had a lockright fail in an 8" diff that knows for a FACT the carrier was in spec BEFORE they installed the locker...

Other than that, pin failure is the most common problem, and an easy fix...

Most people buy Detroits because someone told them they were better... period. But if you want best bang for your wheelin' dollar - my front & rear lockrights would out wheel your "stronger" rear Detroit any day <IMG SRC="smilies/wink.gif" border="0">

Especially if you drive this truck on the street a lot, you really ought to get the Detroit. It behaves CONSIDERABLY better than the LockRite.

Can you install a lock-Right easy or do you need to have a shop do it. I have precision measuring tools, but no experience installing or removing rear ends.

Lockrights are far from being "that bad" for on road manners... But as with any auto-locker they are more noticable the smaller the diameter of the tire.


Lockrights are MUCH easier to insatll - since you are just replacing the spider gears where a Detroit would be replacing the entire carrier.

I have experience with both lockers in 4 cyl carriers. I sheared the 4 pins in my rear Lock-right all at once while only running 32" tires. The Lock-Right clicks and screaches on most of the corners. I now have a Detroit NoSPIN in the rear. It spins 35" swampers and has held up fine. (knock on wood) The tires will chirp around corners but not all the time. As for ease of install. Yes the Lock-Rights just replace the spider gears so it is easy, with the Detroit you just bolt the ring gear to the Dertoit. So they are both relatively easy. I put my 3rd's together I just don't set up the gears. I'm planning on going Lock-Right in the front soon just because I already have one. Oh yes which I might add... Powertrax (Lock-Right) does do a good job warrantying their stuff when it breaks. Thats my .02

The detroit is the strongest Diff short of a spool. Period.

I know a Jeeper that had his LR waranteed 3 times in a month before finally sucking it up and buying Detroits. He's had 2 Detriots on a twin-stick, 9-inch and D44 axles, 35" boggers, a 4:1 T-case, and 401 V8 for 5 years without incident.

IMO, the Detroit is much more likely to survive an axleshaft failure. I've heard of blown shafts taking a LockRite with them (But this isn't on a Yota, so take it FWIW)

Here's how I'd sum it up:

* If I was planning on eventually running in Top Truck Challenge, or running on 8 cylinders, I'd buy a Detriot.

* If I was going to play 'round town and in some sandy washes with a 22RE I'd go with the LR to save some coin.

Can't argue there...

First off - you cannot compare different axles in this conversation. Dana 35c rear axles eat lockrights and EZ lockers like snakc cakes...
For a Dana 35c for examople - you are BEGGING for a lockright failure due not to the locker itself - but to a ntoriously weak carrier, and housing flex...

IMO, the Detroit is much more likely to survive an axleshaft failure. I've heard of blown shafts taking a LockRite with them (But this isn't on a Yota, so take it FWIW)

I will say this is incorrect. Detroits are VERY bad about self destructing when a front shaft lets go (rear ones too for that matter). Seen it happen probably 20 times... not that a lockright is better (I actually think it is, but that is a LONG discussion for some other time) but Detroits are known for failing like this.

I have had my Lockright in the rear toy 8" for going on four years now. I love it and feel that the banging and clanking is a real treat to my ears. I know it id there and awaiting the trails and all the torture that I dish out to it. I don't baby my rig and have yet to have either a Birfield break or the locker. I love the look on peoples faces whan I turn and the axle snaps out of locked position, dirt even falls of the rig <IMG SRC="smilies/biggrin.gif" border="0">

Uh... What? He had a Dana 44 in the front and a Ford 9 in the rear for the entire scenario I've mentioned (All of the LRs and the Detriots he's still got)

I agree with you about the D35. I've run with him for a while, and first met him when he had a 9" rear and the D35 front. I then proceeded to watch him blow four shafts / differentials in two months. Finally tweaked his housing and got the D44. He kept the D35 that long because he had a hook-up on used parts for free.

Got the D44 and threw in a L.R. they have excellent warranty service - I'll give them that. Got it replaced, but went Detriot after the second one died when he blew a Ujoint (1st one did on it's own) and hasn't had a problem since.

I said what I did b/c I've seen that LR die when a U-joint let go. I've never seen a Detriot die at all, but that don't mean it can't happen.

hmmm...well, FWIW, I have Detroits in mine, never had a lock-rite. I have three seperate friends, all with 8" Toyota rears, two out of three have blown them up. On one the cross pin sheared, the other one the teeth stripped. The third one has had his for at least 4 years now and hasn't had one bit of trouble. I don't know the condition of the carriers when they were installed, but they were installed at the same time as a gear change, I would make the assumption that the carriers were fine, as they were installed by a shop.

In my experience, the Detroit is NOTICABLY better behaved on the street.

I hope this is an appropriate question to post on this post, if not, sorry. What exactly, and be brief, is the difference, mechanically, between the Lockrite and the Detroit? Like, which one would be the better choice on an off-road rig? Also, comparing the detroit locker to a Detroit Soft locker, does the SL compromise off-road reliability for street manners? Would a soft locker be a good choice, even for the hardcore wheeler, if the rig was driven off road only? For my last question, how does having a locker affect handling/ traction when driving on-road in snowy or icy conditions? Thx in advance. <IMG SRC="smilies/bounce2.gif" border="0">

I use LR's in my Scout and my Suzuki, never had a problem. As far as behaving, who cares? With all the mods on my rig the lockers would be the least of my complaints if I had any. <IMG SRC="smilies/smile.gif" border="0">

What exactly, and be brief, is the difference, mechanically, between the Lockrite and the Detroit?

The LockRight replaces the spider gears inside your stock open carrier, the Detroit Locker replaces your stock open carrier for a stronger one.

Like, which one would be the better choice on an off-road rig?

They both fully lock up and behave similarly offroad, so either will do the job.

Also, comparing the detroit locker to a Detroit Soft locker, does the SL compromise off-road reliability for street manners?

This is a big misconception about the "Soft"locker. Bad choice of words from Tractech. The SoftLocker IS the old Detroit Locker everyone knows, it was changed several years ago to be quieter and smoother onroad. There is NO compromise, just benefits.

Would a soft locker be a good choice, even for the hardcore wheeler, if the rig was driven off road only?

Absolutely yes.

For my last question, how does having a locker affect handling/ traction when driving on-road in snowy or icy conditions?

I believe this depends on where you live and your definition of snow and ice. When I lived down South, when they got ice storms you needed a tracked vehicle to get anywhere, so it doesn't matter. I uderstand out West you have powdery snow which gives decent traction. Here in the Rustbelt we get snow, icy snow, snowy ice, ice, and more snow (we had snow on the ground from early November to late March this past winter). It's not uncommon for me to wake up to 18" of fresh snow covering slush and ice, just to give some perspective to my following comments.

The Detroit was a bit squirrelly onroad in our snow at first, with an AT and 33's. Just had to take it easy when starting off from a stop, and around turns. On severely crowned roads, it was at times challenging to keep it on the road.

Then I siped my tires and that made all the difference in the world. The rear end stayed planted and in control.

I also believe the AT helps a great deal, the locker action is even smoother than with a 5-speed.

Ok, let the hair-splitting begin....... <IMG SRC="smilies/rolleyes.gif" border="0"> <IMG SRC="smilies/rasta.gif" border="0">

If you had the money, how do ARBs compare to detroits and LRs?
