The EVO MFG JL Dana 44 ProTek Front Axle Truss is specifically designed to give your front axle ample strength to prevent deflection and support the brittle FAD/CAD casting that is integrated into the front axle and prone to failure. The included ¼" steel differential bridge connects left and right truss sections over cast differential center section giving a extremely strong one piece integrated truss system covering the entire axle end to end. This product is manufactured from 1/4" Laser cut steel and CNC press brake formed in strong one piece sections that minimize excess heat and weld shrinkage. Less heat, less warping, easier and faster install. This Truss kit fits both JL and JLU Rubicon Front Dana 44 M210 Advantec Front Axle. The EVO MFG JL C2 Axle Gussets are designed to backbone the axle end forging "Cs" with CNC formed 3/16" laser cut steel on both upper and lower axle Cs keeping them supported and alignments in check. These gussets are a direct fit to JL axle in all models Dana 44 Rubicon (M210) and Dana 30 Sahara/Sports (M186), both 2 JL and JLUs. Wiring retainers included keeping a clean wiring layout.
