ProFloat XD60™ for the 2018-Newer Jeep Wrangler JL

Everyone else’s full-float axle just became obsolete. The Dynatrac ProFloat XD60™ is a proprietary system of axleshaft, housing and bearing technology that virtually eliminates axle-flange bending, even with tires up to 40-inches in diameter. This ProFloat XD60 is a direct bolt-in for the 2018-current Jeep Wrangler (JL).

Dynatrac has once again rewritten the rulebook of axle strength and durability. With the introduction of the ProFloat XD60™ axle, customers can now have the strength of a full-float rear axle without the heavy weight and the need to change wheels. 

Watch this video of shaft testing to see it for yourself:

This all-new advanced axle housing and axleshaft design provides the following upgrades in strength:

• Major bearing offset improvement to greatly reduce cantilever effect of loads at the wheel
• Significantly thicker flange section at the wheel bolt circle
• Much larger shaft-to-flange transition radius, with tapered flange skirts for extra flange stiffness
• Bearing journal is larger in diameter than other performance semi-float axle shafts
• Seal journal is significantly larger in diameter than performance semi-float axleshafts
• Heat-treated chromoly axleshafts

The ProFloat XD60 is available with 35-spline axleshafts.

In addition, the ProFloat XD60 is up to 100 pounds lighter than comparable full-float axles. This is unsprung weight, further improving the on- and off-road driving characteristics of the vehicle.

Because the ProFloat XD60 is not a full-float axle, customers can retain their existing wheel, saving costs when upgrading to larger tires. This new design uses off-the-shelf, heavy-duty F-150 brake assemblies for great performance and ease of procuring replacement components. The brakes are Jeep Wrangler (JK and JL) and Gladiator (JT) ABS/ESP compatible.

The ProFloat XD60 includes all of these standard ProRock XD60^® features:

• Dynatrac exclusive patented ProRock^® nodular-iron, ProRock XD60 center section with optional bearing bores to handle oversize pinion and carrier bearings for elite housing rigidity.
• Low-pinion, standard-cut gearing for ideal rear-axle application
• Optional high-pinion, reverse-cut gearing is available on request.
• More ground clearance than any other axle housing in its class
• Best strength, best ring-and-pinion gear support and stability
• High-capacity carrier-bearing saddle structure
• 7/16-inch cover bolts – cover now adds additional structure to the housing
• O-ring cover seal and hard contact mating surfaces
• 4.0-inch diameter, variable wall thickness, lightweight, chromoly tubing has the highest strength-to-weight ratio compared to any other light-truck axle on the market
• Dynatrac exclusive Dual-Sump High Volume™ (DSHV) oiling system to ensure the outer pinion bearing is never without lubrication
