Fits the following applications:
'07-'17 Jeep Wrangler JK 2 Door Rubicon Models
'07-'17 Jeep Wrangler JKU 4 Door Rubicon Models
Part #: JK4455
Finish: Bare Steel
PATENT PENDING APEX truss peaked top design provides more rigidity than a flat top truss design
Truss is CNC Precision Laser cut in-house from 1/8" mild steel for a lightweight yet strong solution...only 7 lbs
Truss is CNC Precision Bent in-house for a great fitment. Literally drop the truss in place on the axle and it's ready to weld. No puzzle piece assembling*
Designed used 3D models directly from Dana Corp and Jeep for not only an amazing fit but clearances with surrounding components
70% less welding needed than previous truss designs means less warping, faster turnaround, and lower costs
All long seams are bent so you don't need to spend time welding them together
APEX design continues under the OEM coil buckets for complete end-to-end axle reinforcement...an industry first
Dimpled holes provide not only weight reduction but rigidity and strength
Contours to the cast steel differential and can be welded with normal MIG welder and moderate pre-heating and post-heating
Provides worry-free wheeling of up to 37 inch tires on stock JK axles**
Truss strengthens the weakest sections of the axle...under the coil perches, around the control arm brackets, and where the tube enters the casting
Low Profile Design doesn't go over differential and allows usage in vehicles with only slight lift***
Front LCA Skids, Inner C Gussets and HD Trackbar Brackets made from 1/4" steel
Skids, Gussets, and Brackets strengthen or replace weak components of the axle that are prone to failure
NOTE: Jeep offers different variations of axle housings. Please refer to the following diagram for details on which version to choose. If you have one model of a vehicle but have swapped in axles from another model, choose the model that the axles were originally in.
JK3055 - Use on JK Sport/Sahara (Dana 30 front axle) with over 3 inch lift using DRAG LINK FLIP KIT
JK3056 - Use on JK Sport/Sahara (Dana 30 front axle) with under 3 inch lift using factory trackbar mounting location
JK4455 - Use on JK Rubicon (Dana 44 front axle) with over 3 inch lift using DRAG LINK FLIP KIT
JK4456 - Use on JK Rubicon (Dana 44 front axle) with under 3 inch lift using factory trackbar mounting location
NOTE: If your lift replaces your trackbar and mounts to the factory axle bracket (typical with a lift that includes an adjustable trackbar), choose FACTORY HEIGHT BRACKET. If you are doing a DRAG LINK FLIP (which requires a minimum 3" lift and bumpstop extensions), choose RAISED HEIGHT BRACKET.
*Some grinding and fitment may be required when installing this kit. Every axle varies slightly and some fabrication may be required.
**Stock axles have other components that may not hold up to the abuse of larger tires. Artec implies no guarantees that you will not break some component on your stock axles using larger tires. Use at you own risk.
***THIS KIT IS INTENDED FOR VEHICLES WITH AT LEAST MINOR LIFTS (1.5"+ RECOMMENDED) AND AT LEAST 1/2" BUMP STOP EXTENSIONS. CHECK CLEARANCES BEFORE INSTALLING. NOT TESTED IN NON-US JKs or RIGHT HAND DRIVE AXLES.**
NOTE: This kit requires general welding and fabrication skills including welding to the cast center section and cast inner c's. Welding should only be done by a competent welder. Artec Industries implies no guarantees or warranties and is not liable for improper installation.
** In rare and extreme cases, the truss may come into contact with oil pan. Prior to operating the vehicle, remove the coil springs, cycle the suspension including full compression of both sides simultaneously and add bumpstop extensions to prevent damage to oil pan.
