Dynatrac ProFloat XD60™ Rear Axle for 2018–Current Jeep Wrangler JL
Everyone else’s full-float axle just became obsolete. The Dynatrac ProFloat XD60™ is a proprietary rear axle system engineered to deliver the strength of a full-float axle without the added weight or the need to change wheels. Designed as a direct bolt-in upgrade for the 2018–current Jeep Wrangler JL, the ProFloat XD60 virtually eliminates axle flange bending, even with tire sizes up to 40 inches.
By completely rethinking axle housing geometry, bearing placement, and axleshaft design, Dynatrac created a rear axle that significantly improves durability while reducing unsprung weight. The result is improved on-road handling, better off-road control, and long-term reliability under extreme loads.
Key Features:
-
Major bearing offset improvement to reduce cantilever load at the wheel
-
Significantly thicker axle flange section at the wheel bolt circle
-
Larger shaft-to-flange transition radius with tapered flange skirts for added stiffness
