The Dynatrac Elite ProRock XD60/80 Axle-Set™ stands alone among all other 4x4 drivetrain options. It is the very best 4WD drivetrain technology that money can buy. You simply cannot find a stronger axle solution than the ProRock Elite Axle-Set™. The U.S.-made bolt-in unit is lightweight and has higher ground clearance than its competitors.

The ProRock XD60/80 Axle Set™ is for Jeep Wrangler JL owners who will not settle for anything less than the very best drivetrain durability, quality and extreme performance for running tires in diameters from 37- to 44-inches. If you are a highly experienced and skilled off-road driver who regularly engages in very technical off-roading with their friends and family, you enjoy taking on the hardest trails and the most difficult and challenging obstacles, this is the Axle Set for you.

The ProRock XD60/80 Axle Set is designed specifically for large JL builds with very large tires, high-performance engine swaps, superchargers, high-torque diesel engine swaps, deep gear reduction and transfer case ratios numerically higher than 4:1.
