Pocket Locker

I have a 2006 Prerunner, and I would like to improve my traction. I spoke to a mechanic who suggested a "pocket locker." The term is new to me and a search of the forum didn't turn up any information. It seems to be a partial differential gear replacement. Does anyone know whether this is a good option?

 

he might be referring to a lunchbox locker? you'll have more luck researching that term

 

Im going to assume he means a lunchbox locker like the powertrax no-slip or something similar. Never heard anyone use the term pocket locker though.

It's down under they call them things "lunchbox lockers". They call 'em that cause lots of Aussie's install them and with the improved traction go out in the bush and run down kangaroos for meat hence "lunchbox". Here's a link to read.

Detroit TruTrac will do you better

 

For a pre-runner I might suggest a true selectable locker like ARB air locker or similar

 

Pretty sure it's called a lunch box locker b/c you're just replacing the parts inside the carrier to make the locker and the carrier is considered the lunchbox.
But I like your theory better.

 

This. On a DD 2wd truck a tru trac will be much less of a pain than a lunchbox

 

I've think the tru trac is probably the best option in this category.

I believe this is what they are talking about. Not an easy install, but can be done without having to re-set up your gears. Also with basic hand tools.

 

Wow! Thanks, guys, for all the great info. I'll do some research.

 

not in stock....

you had my hopes up
but good thinking on summit racing. I keep forgetting about those guys

 

Amazon work for you? Same price:

$318 PowerTrax 1615-LR Lock-Right Differential Locker, 30 Spline, Fits Toyota 8"/8.4", Compatible with Tacoma, Tundra, Sequoia, T100

https://www.amazon.com/Powertrax-16...t=&hvlocphy=1015502&hvtargid=pla-634372319437

 

I appreciate the link, but Amazon says its "currently unavailalbe"

also I'm in Canada, so shipping / duties would suck.
I was excited for Summit having it due to me already having an account and how they account for shipping and duty fees so I know what my "out the door" price is.

no worries. If we're gonna be honest right now, I'm still closer to Mall Crawler, then Rock Crawler.
I can wait a little bit

 

Strange, It still shows one in stock and it will let me buy it now. Not sure if being in Canada has something to do with though.

 

That's a solid reason to go limited slip, and Not go lunchbox locker.

BTDT, with Aussie Lockers in my XJ. They're bitchin cool, cheap, and work well. But if your truck is a pavement pounder primarily? A lunchbox is probably not what you want. Just my $0.02

 

Nah just what popped up when I googled just to give him an idea.

 

They do have very "unique" driving quirks on pavement for sure. I had one in my 03 and when it would "pop" it'd scare the living shit outta ya. You'd swear to God you broke something. Also wear tires out.

 

The lock rite I had in my 4runner would only unload on left turns. It so so strange. And when it did it sounded like gun shots. I learned to push in the clutch after I got started and coasted through the turn to try to avoid it.

 

If you live in Canada which I assume means you see snow every year, I would NOT put a lunchbox locker on a daily driver.

Lunchbox lockers can get really squirrelly on slick roads and make your day go down the drain real fast. Lunchbox lockers engage when a certain amount of torque is applied, and if it engages on a slick surface like say, during a turn...not good.

Not to say you can't do it, I had one in the rear of my old truck and had to adjust my driving style a little. But I live where the roads are dry most of the year


Limited slip or selectable locker would by my suggestion. Selectable is the way to go for maximum offroad traction, but they are pricey
