EVO MFG JK ProTek Rear Axle Truss Although less common than the front, the JK rear axle is known to bend causing a costly axle replacement. The EVO MFG JK ProTek Rear Axle Truss is designed to give a rigid support connecting both driver and passenger side axle tubes via a one piece truss system contouring the differential center section making no need to weld to the differential casting which requires a specialty welding process for proper adhesion. This gives full side to side axle tube support. Manufactured from laser cut 3/16” steel and CNC press brake formed in one piece to minimize welding labor, excess heat, and axle warpage.
