Dynatrac ProFloat XD60™ Rear Axle for 2007–2018 Jeep Wrangler JK
Everyone else’s full-float axle just became obsolete. The Dynatrac ProFloat XD60™ is a proprietary rear axle system engineered to deliver near full-float strength without the weight, bulk, or wheel-change requirements of a traditional full-float axle. Designed as a direct bolt-in upgrade for the 2007–2018 Jeep Wrangler JK, the ProFloat XD60 virtually eliminates axle-flange bending, even with tires up to 40 inches.
By combining advanced axle shaft geometry, housing design, and bearing technology, Dynatrac delivers exceptional strength, durability, and ground clearance while retaining compatibility with factory wheels and JK ABS/ESP systems.
