Which is better quality - OEM Rubicon Lockers or a good Aftermarket?

I am thinking of trading my 2010 Sport for a 2012 Rubicon.

Mostly because I want lockers and the 4:10s.

But, if I can spend about the same money as my down payment for the new rig to put lockers in my Sport, it is a wash.

But, if the quality is better for the OEMs, it might sway me further.

Thanks

Scott

Can't offer any info on the OEM lockers but when making your decision, don't forget the D44 front and the pentastar on the 12 rubi

The factory rubi locker is also put together on a factory line, likely set up better than a typical aftermarket installer. This matters when you are setting up a ring and pinion.

Always consider resale before you spend $ on mods. A lot easier to get most of your money back on factory equipment.

The rubicon lockers are known to be finicky and only work in 4L under 18mph. They should not be the sole reason for buying one. D44 and rock trac tc case are the best reasons.

The factory lockers are made by a company called GKN or something and they are probably made in China (no proof). IMO, they are less quality than some aftermarket lockers and just cause they are installed on the factory line doesn't mean they are set up better. In fact there are tons of stories of OEM lockers having problems engaging and disengaging. They also will not hold up to the abuses of rock crawling with 37's or bigger. It isn't a rule of thumb that they will all fail but they are set up mainly for a stock Rubicon and that is it. Some better brands out there are Detroit and ARB. Eaton's E Locker for the D30 is a good one too. There is also tons of positive feedback on Yukon Zip lockers. OX makes a strong product too.

OP to regear and add lockers will cost you depending on setup. You can go as cheap as lunchbox lockers, which use OEM carriers, 100% locked and they run about ~$300. They work great and can be installed by a skilled home mechanic. Auto lockers like the Detroit and Grizzly replace the carrier with a stronger one and run anywhere from $500 to $600 give or take. Then selectables will run $750 - $1000. Gearing is about $600 in parts figure labor too and you are looking at a good $2,000 to $3,000 for parts and install. Estimates of course

Without a doubt, factory lockers are not nearly as good as aftermarket ones such as ARB.

Stick with a sport and add your lockers...

You can buy a sport and throw in a Pro Rock44 and still come out cheaper then buying a Rubicon.

For lockers, ARB hands down.

Ruby is nice, but dont discount your sport. Keep in mind that the D44 front, has only a different pumpkin and axles with larger ring gear. The axle tubes and Knuckles are virtually the same on your currant D30. Your JKs D30 also is the next generation and contains stronger reverse cut gears, unlike the old TJ D30. If you didnt already own a Jeep, id say jump into a Ruby, you wont be disapointed. But, since u got a Jk already, build it up. Your custom rig could be potentially better then a store bought Ruby. Its all opinion amd preference based. But id vote to build what you have. Tons of options to fit your budget.

Rock Trac is a nice Tcase option. D44 as equiped and built for the Ruby from the factory isnt the wonder bread were use to as equiped in the old chevy and ford rigs of the 70's. The Dynatrac built D44 as a comparison seems much more stout, and shares no D30 components. Either way, build the heep or Buy a Ruby, dont see dissapointment on either choice.

I have a 2012 Sport, I would of got the Rubicon if I could of afforded it, however I will have a lot more fun building my JKU to be better that a stock Rubicon. I cant really say I would not trade up. But the aftermarket parts surely would be better than the OEM, but what do you plan on doing with your rig? Hard core rock crawling or Trail riding. My Sport has yet to let me down even in stock forum.

Factory lockers have a 5 year / 100,000 mile warranty. Haven't been disappointed so far.

To give you an example of upgrade costs TeraFlex quoted me around 5500 to upgrade my D30 and install 4:88's or 5:13's and ARB lockers front and back. The price includes everything including the ARB on board compressor.

Lol, if you put 35's on those fancy factory lockers they will be voided. I promise you that.

Ask yourself why all the extreme guys have aftermarket lockers and not factory ones?

If you're thinking about putting lockers in, don't waste your time and money on buying a Rubicon.

$2500 of that is labor, the parts will run you about $3k and probably a weekend of work. DIY!!!

Not taking away from a Rubicon but as with most vehicles stock is not the best on the market. Not the worst either but usually aftermarket has better parts as long as it's from a good company. I think a Rubicon is a awesome stock Jeep but if you want to build one you can do better. Really the TC is the only piece that a Rubicon can offer that you can't do much better without getting real expensive. The E-Discos can fail alone with flaky lockers when serious off roading is done. Not to mention, building a Jeep into a lean mean off roading machine is just fun and makes it personal. I wouldn't trade mine for one but would trade my Duratrac's for some 35 MT/R's

There is always that one problem child even with the best. But ARB is one of the best lockers out there. If I had to guess the locker is rejecting the FJ

Personally, since you already have the '10, I'd do 1 of 2 things depending on all your reasons.

If you're looking at upgrading to a '12 b/c of the engine too, I'd just go with a sport and upgrade it yourself.

If all you care about is the lockers, just do the regear and lockers on your '10 and call it a day.

We paid 38k for an '11 Rubi. This year I paid 35k and came home with a sport that already had lift, tires, new driveshafts, and control arms. It would've cost me a lot more money to do all that than it will to install a set of lockers and a regear.

That's just my 2 cents. The Rubi is nice, but there's nothing on it you can't do yourself cheaper. Hence I didn't buy one the 2nd time I picked up a JKU. I never get the attitude of it's not a real Jeep unless it's a Rubicon. We all did just fine before Rubi's even existed.

lockers stock or after market

No choice here. I got lifetime warranty on my 2012 Rubicon. I will keep the drivetrain and all moving parts stock.

I know what his problem is. He installed it in an FJ.

What are you talking about?

I have 35s and 5.38s installed by a gear shop. My rear lockers went out and my dealer fixed them under warrantee.
