Confirmation, Gear swap and rear diff

[O.R.T.]

I'd love to swap my factory asd for the tor-sen style.

That ECTED Max looks like the ultimate

In normal operation, it's a limited slip. Flip a switch and its a full-on locker! How cool is that?

I thought that a few years ago until I started looking into buying one. It turns out they pretty much never work after a year or so. That was about 7 years ago though so they might have improved them.

Finally found the article, Post-SEMA blurb about the Auburn I was looking for. Sorry it took so long but been out sick since Thursday night and this stuff's usually in a work folder. (This is basically similar script to what DavidRam shared above.

Auburn Gear First to Offer Aftermarket Alternative for Post-2010
Chrysler 9-¼ ZF Limited-Slip Differential

Auburn’s new 9-¼ limited-slip differential broadens consumer choice and delivers
superior strength and performance for about 25 percent less than OE diff.

AUBURN, Ind., Aug. 19, 2014—Auburn Gear, Inc., a leading U.S.-based manufacturer of highperformance
differentials, introduced its new aftermarket, limited-slip differential replacement
for vehicles with the Chrysler 9-¼ ZF rear axle built after 2010. Auburn’s new aftermarket 9-¼
differential is the first to market and is designed for easy installation and higher performance
than the original equipment.

Until now, those wanting a limited-slip differential on certain Dodge, Jeep and RAM vehicles
made after 2010 had to either specify it as an option in place of the standard Chrysler 9-¼ ZF
open differential or pay to have an OE 9-¼ ZF limited-slip retrofit performed. Cost was often a
barrier, and the OE-made posi-track was the only aftermarket option available.

“Folks would call me and ask about retrofitting their trucks, but once I quoted them a price for
the OE replacement, they’d often change their minds,” Ron Hill, sales manager for Pyle Bros. of
Baytown, Texas, said. “We’ve always been impressed with both the quality and operational
characteristics of Auburn’s differentials, and their new 9-¼ gives me a lower-cost, higherperformance
alternative for my customers.”

Auburn’s new high-torque-bias limited-slip differential is engineered to surpass the abilities of
the OE differential, making Auburn’s new differential even more attractive to those who want to
upgrade their drivetrains and their performance capabilities. Auburn’s design provides superior
bias torque to the high-traction wheel and is compatible with gear ratios of 2.71:1 and up.

Aggressive off-road driving over difficult terrain can challenge some differentials to the breaking
point. Auburn’s new 9-¼ limited-slip differential is designed to stand up to significant
punishment and gives drivers smooth torque-sensing operation with correct bias ratios
engineered to outperform other standard differentials.

“I expect Auburn’s new diff. to be stronger overall and to deliver better traction, so we’ll see less
one-wheel wonders,” Jeremy Ayers, president of J.T.’s Parts & Accessories of Cashmere,
Washington, said. “Auburn’s products have the best warranty in the business, and the fact that
their products are made in the U.S.A. is important to our customer base.”

Auburn Gear has been manufacturing its products in Auburn, Indiana, since 1982. The company
engineers a wide variety of performance-enhancing and high-performance aftermarket
differentials and believes that being exclusively American Made is one of its unique advantages.
All Auburn differentials are backed by the company’s one-year warranty and exclusive
Differential Replacement Exchange (D-REX) Program. According to the terms of the D-REX
Program, Auburn will replace any differential within the first four years of purchase, regardless
of circumstances. The replacement differential is one-third of the original cost (that is roughly
the equivalent of the price of a competitor’s clutch pack). The replacement differential comes
fully assembled, tested, certified and ready for installation. No rebuilding is required, and thus no
mixing of old or worn parts with new parts is necessary.

“We watch the market closely, and we saw the need for a competitively priced aftermarket 9-¼
limited-slip differential,” Jamie Forrest, senior product engineer for Auburn Gear, said. “I’m
excited to say that we brought our solution to fruition within 9 months of its inception, and it’s
the extra effort involved that has allowed us to be first to market with our aftermarket 9-¼
solution.”

Auburn’s 9-¼ limited-slip differential, model number 5420142, is expected to begin shipping on
or about Sept. 30, 2014. Auburn’s new aftermarket differential can be used to replace the opencase
or limited-slip differentials on Chrysler 9.25 in. ZF axle models. Auburn’s new differential
is compatible with the 2011 - 2014 Dodge Durango Citadel, 2011 - 2013 Dodge Durango Crew,
2011 Dodge Durango Express, 2011 Dodge Durango Heat, 2014 Dodge Durango Limited, 2011

Also of benefit, apparently MOE's, one of our forum sponsors IS carrying them: Auburn Limited Slip Differential for 9.25" Rear

Auburn Gear's high bias limited slip differentials outperform standard OEM differentials hands down. They deliver more traction and faster engagement for controlled power transfer and lightning-fast reaction to changing conditions. No matter what your application - the LSD is engineered to provide smooth torque-sensing operation with bias ratios to meet your performance needs. This superior performance is achieved through an innovative cone clutch design which transfers more power to the high-traction wheel for quick acceleration and tight cornering. The high performance series is an excellent replacement for the standard original equipment differential for quality traction enhancement. The Auburn cone clutch design offers increased durability and performance in normal street use.

•Cone Clutches Coupled to Beveled Side Gears
•CAE/CAD System Design Complete with Finite Element Analysis
•Smooth Torque-Sensing Operation For More Traction & Faster Engagement
•Includes One (Two For Some Applications) Bottle of Auburn Gear Friction Additive!
•Industry Leading 1-Year Warranty

This unit fits all 2002-2010 Ram 1500 trucks (Except Mega Cab Models).

Suggestion, MODS/ADMIN, can you please see if a tie-in to the above referenced threads is possible, or even consider tying in all three of these topics under a new "STICKY" entitled "DIFFERENTIAL/TRACTION" withing the Engine and Performance as although this specific subject does fall under "Performance" is specifically falls into the "Drivetrain" category. From my experience people may not be keen on knowing to look in topics under a new "STICKY" entitled "DIFFERENTIAL/TRACTION" withing the Engine and Performance for a drivetrain topic.

Off to open my own topic on this, just so I get to be Mr.StickyCommander.

did they give you areplacement?

 

[RedSRT4Me]

235mm = 9.25in

The rear ends are not 8.25in, otherwise this would be a pretty nice option. The stock LSD is a *************, just FYI.

What happen to your stock LSD?

What happen to your stock LSD?

The clutches are pretty light duty in the OEM limited slips.It's okay for probably 90 % of owners,but the off road guys and the dragstrip guys are cooking the stock OEM's fairly often.Right at the moment you're best option for a bulletproof posi unit,is to spring for the high dollar Detriot True Trac unit.You can put a True Truac in the later ZF diffs,but it's not cheap,roughly in the neighbourhood of $1500.00 just for the parts to do,then labour on top of that to have it installed.
