Artec Industries JK APEX Front Axle Trusses
Artec Industries JK APEX front axle trusses introduce 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 have led 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 the axle, an industry first in an OEM axle application. The JK APEX truss has been tested and proved to hold up to both extreme applications and daily driving. Product details: * 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 in. 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 using 3-D models directly from Dana Corp and Jeep for an amazing fit and 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 weight reduction, 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 in. 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

Trail-Gear Rock Assault Custom Axle Housings
Years after releasing their successful Rock Assault 9 axle housing, Trail-Gear decided to add a Toyota 8 in. version to the Rock Assault lineup. This housing is built to the same specifications as the Rock Assault 9 axles; however, they're built to accept the popular Toyota 8 in. differential. These housings have been tested in W.E. Rock, CalRocs, and King of the Hammers—so you know they'll stand up to the toughest terrain on earth. Trail-Gear started with a 1/4 in. thick formed shell for the center section made from A36 steel. This is a high-strength, low alloy, structural steel plate with a minimum yield strength of 36,000 psi. All of this is attached to an equally strong 1/2 in. thick faceplate for anchoring the DOM axle tubes. The axle tubes are secured by the industry's first 3-Point Attachment System, giving the tubes superior support and engagement into the center section. Trail-Gear also faces the center section to ensure your differential mounts flush against the axle housing to prevent any leaks. Rock Assault Fabricated 8 Housings are offered with 3.5 in. O.D. axle tubes with your choice of 1/4 in. or 3/8 in. wall thickness. NOTE: The housing is shipped with no ends. Housing ends must be sourced and installed to complete axle. Portal style ends are commonly used for this application.
