New Product Announcement – Challenger / Charger SRT

Torsen is pleased to announce the introduction of a model – 975420-0195A, for the Dodge Challenger and Charger models that use the Getrag 226 axle.  This axle is commonly found in the SRT8 cars, as well as some R/T and other assorted models with performance packages.  This T-2R design is architecturally related to our Ford Super 8.8 & Chevy 5th Gen Camaro products.  Torque bias ratio is approximately 3:1 in drive, 2:1 in coast.  Available now:

New Product Announcement

Wow, 2018 has been flying by.  We’re more than a half the year gone, and this is the first time we’ve had a chance to post anything here.  But there’s good news – announcing new products!

Peregrine High-Torque Differentials for S550 Mustang

We mentioned this in passing a while back.  Under the code name “Peregrine”, we have developed a pair of high-torque capacity T-2R differentials for 2015 and newer Mustang models.  These differentials have 6 planet gear sets, and as a result, can boast a significant increase in gear strength rating, fatigue life and impact load capability.  These are ideal for severe-duty situations, such as road racing or drag strip use.  Peregrine models are available for both 3.15:1 final drive ratio and 3.31: and higher ratios.

T-2R for JK Dana 44

This seems like such a no-brainer, I don’t know why we didn’t do it sooner.  We now offer a T-2R model specifically for the Dana 44 axle used in Jeep Wrangler JK models.  The JK uses a version of the Dana 44 with 1/2″ diameter ring gear bolts; whereas other versions use 3/8″ or 7/16″ bolts.  We’ve made this to accommodate the larger bolt to allow a direct fit.  Fits 2007 and newer Wranglers with rear Dana 44, with both 3.21 & 3.73:1 OEM final drive ratios.

More New Products!

Announcing more new products!

JTEKT Torsen is pleased to bring back the Type-1 differential for the 31-spline Ford 9-inch axle.  We were able to produce a limited quantity of these babies, so once they sell out they will be gone.  The Type-1 is the original, crossed-axis Torsen, which has naturally high TBR characteristics.  Torque bias ratio on this unit is approximately 4:1, and is suited for assorted circle track or street rod applications.

We are also adding a brand-new T-2R model for the Ford 9.75″ axle.  The 9.75 is commonly found in F-150 models starting from way back in 1997.  It is also used in the Expedition and some Transit vans.  This is a high-TBR model, primarily intended for off-pavement use.  Torque bias ratio is approximately 4.5:1.

Ford Announces Torsen in F-150 Tremor

Ford Motor Company announced the addition of the Torsen differential to the new 2021 F-150 Tremor off-road model.

The Tremor, a sort of goldilocks level offroad package that offers more capability than the FX4 but at a lower price than the full-tilt Raptor model, adds a lift, 33″ tires, specific shocks and springs and other offroad goodies to the trim level. It also borrows some of the Raptor’s better drivetrain bits, including the Torsen for the 8.8″ front axle.

A Torsen New Year

With 2016 officially on the books, we all like to take a moment to reflect back on what that year brought us.  Here at Torsen Intergalactic, a lot of things took place that were noteworthy.  Most obvious to all of you was that a brand new website was launched, replacing that clunky old frame-based site that looked it was created around 2000 (because it was).  This has given us better ability to hawk our product, tell you why its awesome, communicate to readers (by way of this news page), and of course, has improved your ability to connect with us.  But 2016 also brought us a number of things that you wouldn’t see from your side of the internet.

In 2016, we ramped up to volume production for the Ford Mustang GT350, as well as relaunched the front differential for the F-150 Raptor (now a $500 stand-alone option on Ford’s website).  These, combined with the ongoing Mustang GT differential production have served to significantly increase our OEM sales volume.  That led us to hiring more staff and adding more equipment.  We added a new gear cutter and a new gear inspection machine.  We’ve contracted to have a new assembly line as well.  Inside the Torsen Cosmic Headquarters building, we’ve knocked down several walls, rearranged the machine shop and rejiggered the assembly area to accommodate the new machines in a sensible way.

On another front, we had an excellent turn out and response to our booth at the SEMA show in Las Vegas.  We attended the PRI show for the first time in a long time.  We’ve added several new models to our aftermarket line, and we’ve identified segments of the market that we feel are ripe for new offerings.  Look for additional new models in 2017.

That’s not to say its been all rainbows and unicorns.  There have been issues along the way – some rather significant.  However, it wouldn’t be proper to discuss these in polite company.  Needless to say, said issues have been resolved and the world is now as right as it should be.  So where does that all leave us going forward?  Well, we expect 2017 to build on what we’ve achieved in 2017 and ring in new areas of growth.

For starters, the new assembly line is being installed as we speak, or, at least as I type this.  Another new gear cutting machine is on the horizon, scheduled to land in late spring.  This piece of equipment will have several unique features that will allow us to make gearing components unlike any made by those other helical gear makers, and will allow us to fully produce whatever we need in-house.  That will truly open up our prototype and low-volume manufacturing flexibility.

Also, as mentioned above, we’re planning several new aftermarket models to help round our our product list.  We intend to offer product for segments that are sorely lacking in our current line, while also expanding our motorsport offerings – particularly in off-road racing, as well autocross, track use, etc.  At this time, I think its fair to say that we’ll be back at SEMA in November, but right now that seems a long time away.  Either way, we’re also working to be more responsive to customers, both in terms of listening to what you want, but also in addressing general day to day communications.

All told, 2017 looks potentially quite bright, with projected volume increases, sales expansion and newfound manufacturing capacity that’s coming.  We look forward to working with you in the new year!

New products available!

Wow, this year is going by fast.  Here we are in the middle of February already – and posts on the news page have been a little lax.  Well, good news: several new products have been added to the Torsen webstore.

Has the thrust block for the Torsen diff in your Boss 302 gone on vacation without you?  Perhaps your pooch buried it in the backyard, or maybe your buddy decided to play a practical joke on you.  Either way, you can’t finish installing your Torsen into a Ford 8.8″ axle unless you have the center block.  The block, also called a thrust plate, not only spaces your axle shafts apart, it also supports the thrust load of the differential’s side gears during operation, and as such is essential.

Many times, these blocks get lost during the time between removal and reinstallation.  Well, Torsen can help.  Replacement thrust blocks are now available in our webstore, and include a replacement retaining bolt.  This block kit fits the Torsen differential found in the 2012-14 model year Mustang GT, Boss 302 & GT500 models (Ford part number CR3W-4026-AB), the same model sold by Ford Racing (part number M-4204-MB), as well as all recent T-2R models sold for the 8.8” axle (Torsen part number 975420-0200AF).

We have also added a split thrust block kit that fits Torsen differentials for the GM 7.6” axle application.  This kit is intended for use in OEM-production Torsen units found in 1999-2002 Camaro & Firebird models, with identifying numbers starting with 9021-, 9022-, 9023- & 9032- and will also fit late T-2R applications for the same axle (part number 975420-0315E).  This two-piece block is split into two half-thickness blocks, allowing the installation of ring & pinion gear sets with ratios numerically higher than 3.42:1.  So, it you want to install 4.10 gears, this is your ticket.

One additional new product – we now have available direct-replacement differentials for the late Ranger FX4 Level-2.  These are complete assemblies, and only fit Ranger models with 31-spline axle shafts.  They can also be used in older Explorer models with a solid rear axle, but are not compatible with IRS applications or Mustang axles.

Availability of Torsen® Differential for Ranger Dana 35

Rochester, NY – JTEKT Torsen North America, Inc. is pleased to announce that the Torsen® Type-2 differential for the Ford Ranger & Explorer version of the Dana 35 axle is back in stock and available for purchase. This differential, which fits the unique axle specific to the 4WD & AWD models of 1995-2001 Ford Explorer, 1997-2011 Ford Ranger, 1995-2001 Mercury Mountaineer and 1997-2009 Mazda B-series truck. The Torsen part number for this unit is 975420-0207B.

This unit was first developed to support Ford’s Best in the Desert race teams, way back in 2002.  It was used by several teams, including Rob MacCachren & Steve Olliges, as well as the LASD team.  Having a Torsen in the front axle also made a great compliment to the factory Torsen Type-2 that is used in the rear end of the late Ranger FX4 Level-2.
