# Artec Industries JK4457 APEX Front Axle Ultimate Armor Kit D44 Raised Trackbar Jeep Wrangler JK for 2007-2018 Jeep Wrangler / Wrangler JK ### Performance Overview JK APEX Front Axle Truss - A new era has begun with the arrival of the APEX Truss! Artec Industries is proud to announce the next generation of Patent Pending axle trusses. This series of trusses not only builds on our experience as the world leader in axle truss design, it brings it to a whole new level of cost savings, strength, weight savings, simplicity of installation, precision fitment, and complete axle protection never before seen in the industry. The key feature that sets the APEX truss apart is its unique peaked shape top which provides extra rigidity to the whole truss while allowing both a reduction in weight (vs using a thicker material top) and eliminating long weld seams. Previous versions with long weld seams can be lead to extra weld warping of the axle, longer install times and can be inconsistent. This peaked structure not only applies to the axle tube between the coil perches but extends underneath the coil perches as well, forming a complete truss from end to end of axle, an industry first in an OEM axle application. The JK APEX Front Axle Truss has been secretly tested for over a year and a half proving that even though the truss is lighter weight, the peaked structure of the truss holds up to both extreme applications and daily driving. The new JK APEX Front Axle Truss is the epitome of low cost, easy and quick to weld, simple, strong, and complete solutions for making your factory Jeep axle take more abuse than originally intended. You want easy insurance for your axle? The JK APEX Truss provides it. JK Front LCA Skids These heavy duty skids are designed to take serious abuse and reinforce your JL front axle lower control arm brackets. The 1/4 inch thick precision cut and formed components of this setup mean they'll install easily and protect your brackets and lower control arms. JK Inner C Gussets These heavy duty inner C gussets are designed to take serious abuse and reinforce your front Dana 30 or 44 JK Inner C's. The 1/4 inch thick precision cut and formed components precisely contour and wrap around your inner c and add rigidity. JK APEX Trackbar Brackets One of the weakest components of your factory axle is the axle side tracbar bracket and it's typically one of the main reasons for death wobble. Our new Heavy Duty Tracbar brackets are designed to work with our new APEX Truss and eliminate the issues caused by weak factory brackets. They are seriously beefy and ready to take the abuse not to mention raise your steering stabilizer up and out of the way of rocks. For those running smaller lifts and are using an adjustable tracbar mounting to the the factory location, choose Stock Height. For those with taller lifts that require a Drag Link Flip, choose Raised Height. How is this better than the Regular Armor Kit? This Kit includes entire replacement LCA brackets and Shock brackets whereas the regular Armor Kit just adds a skid plate to the factory LCA brackets. Included in this kit: APEX Front Axle Truss Front LCA Skids Inner C Gussets APEX Heavy Duty Trackbar Bracket Features include: 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 inch 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 percent 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 inch steel Skids, Gussets, and Brackets strengthen or replace weak components of the axle that are prone to failure Raised Trackbar 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 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 inch 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 (2.0 inch and up reccomended) and at least 1/2 inch bump stop extensions. Check clearances before installing. Not tested in non-US JKs or right hand drive axles. 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. Some grinding and fitment may be required when installing this kit. Every axle varies slightly and some fabrication may be required.
