Looking to run larger than factory tires and hit some hard trails in your JL or JT? The M210 JL/JT Front Axle truss is the next upgrade for you! This truss reduces deflection of the axle housing, and ties in everything from one end to the other to prevent the dreaded bent or broken front axle.
Not only does this address the common failure point of the FAD Cast section (Front Axle Disconnect failure as seen above) found on factory JL/JT front axles, but this truss also goes above and beyond by going over the top of the differential to tie the driver side tube, passenger side tube and cast center section in to one another. This optional section is completely bolt on and removable to give you proper access with tools to your upper control arm bushing that is pressed into the housing above the differential.
Optional Upper and Lower C Gussets are offered as well to strengthen your outer "C"s where the ball joints are pressed into the housing. This truss is laser cut and precisely formed from 3/16" steel for a great fit, and is designed to work with the M210/Dana 44 Advantek Axle found in most 2018+ Rubicon trim JLs and JTs. Jeep has begun to introduce changes to the housing center sections with the introduction of Mojave JTs/Xtreme Recon JLs and some minor modification may required on these later housings.
This is a DIY kit that requires welding and fabrication. If you are not comfortable/experienced with welding to cast, please work with an experienced off-road shop with a competent welder to complete the process of welding this truss to your axle housing.
**Includes C Gussets and Rear FAD Tie In Bracket. Does NOT include Upper Truss/Differential Tie In.**
Additional Details
*If you completed an engine swap on your JLU, a 1.5"+ lift may be required!*
Products are designed and fabricated to fit vehicles that have varying tolerances from the factory, minor hand fitting may be required.
Truss products are shipped bare metal and ready to weld! Bare metal products may have scratches or surface imperfections as a result of raw material handling, manufacturing, and fabrication. Additional finishing, sanding, and prep work may be required if you wish to also have them finished with a smooth powder coat or paint.
Projected lead times are estimates only, and are subject to changes due to production realities, including material and labor availability and sudden variability in order volume. Lead times are not guaranteed, but we do guarantee that we are hard at work trying to produce the best product we can and get it into our customers’ hands as quickly as possible.
JL/JT M210 Truss FAQs
Is a lift required for clearance to suspension components?: That depends on which components you intend to weld in. Lift is less important than bump stop additions however in this case. To weld in everything, the upper bridge section of the truss will require a 2" bump stop addition. If you're opting only to weld in the lower profile sections, a 1.5" bumpstop addition is recommended. No Lift is required for the outer "C" gussets. We do suggest cycling your suspension and testing your bump stops each time you make a change to the configuration of your vehicle.
Can I start with the base truss and add the other components later?: Yes. Any of the options that are available can be added on later to this system. Please note that the FAD Rear Tie In Bracket requires a FAD Delete to be done prior to it's installation.
Is a FAD Delete Kit included when the Rear FAD Tie In Bracket is ordered?: No. A delete plate is included, but it will require the use of an aftermarket 1 piece axle shaft, in addition to the use of a tazer/programming from a dealer in order to properly finish the deletion.
How does a FAD "Delete" Plate work?: A FAD Delete replaces the electronic module/shift actuator and fork mechanism with a delete plate. Mopar/Factory 392 and 4xE delete plates have a shift fork that is permanently in the "engaged" position and still utilize a 2 piece passenger side shaft in most cases. Many aftermarket delete's use a 1 piece shaft, and eliminate the need for a shift fork at all.
Can I delete the entire FAD casting from the housing by retubing?: With enough fabrication/machining anything is possible; but the short answer is still NO. Even with an extensive amount of fabrication, the passenger side axle shaft seal is integrated into the FAD casting to bring oil to the FAD actuator. There is no provision to install an inner axle shaft seal in the differential center section like on most Dana axles. Without this seal, your differential would not stay oiled properly.
How much height does the optional bolt on/upper truss piece add?: It adds a total of 1.5" of vertical height above the differential at the ring gear; however it sits lower than the factory upper control arm mount and therefore does not increase the vertical height of the housing overall.
Does this effect upper control arm bushing accessibility?: If you are installing the upper truss component that is bolt on, it may need to be removed in order to use proper installation tools to remove and replace the upper control arm bushing on the driver side of the housing. The passenger side upper control arm bushing and other serviceable items are unaffected.
Are the upper C gussets bolt on?: While the upper C gussets do tie into existing holes on the outer C's, they are intended to be fully welded. The upper bolt locations are pre-threaded from the factory, and the lower bosses usually are not yet tapped and will require thread tapping before they can be used.
Will this work on my Mojave/Xtreme Recon/392?: Minor modifications will be required in fabrication and welding if you have a Mojave/XR/XR392 model or a JL/JT vehicle that comes with one of these redesigned housings.
Will this work on my M186 Sport/Sahara/Willys Housing?: We have not yet verified fitment of the base truss or C gussets on the M186/Adantek Dana 30 Housings found in most Non-Rubicon or Export/International Market JLs/JTs. The differential tie in bolt pattern is *NOT* a match, so we can confirm that the upper truss components will not work at this time.
Will this work on my Narrow Track/Non-Rubicon M210 Front Dana 44 JL Housing?: Due to the difference in axle width, and the many changes that originate at the factory, the C gussets we offer will not work on the narrow track/non-rubicon JL/JT housings in most cases.
