Never before have these two axles been available as a package set.\u003c\/p\u003e\u003cp\u003eThe ProFloat XD60 rear axle was engineered to provide the strength of a full-float rear axle, but without the heavy weight – it’s up to 100 pounds lighter than many full-float axles. It features an advanced-technology housing that virtually eliminates flange bending, even with tires up to 40 inches in diameter. \u003c\/p\u003e\u003cp\u003eThe ProRock 44 front axle features 60-class 35-spline inner axleshafts and 1480 axle joints – these are the same sized shafts and joints used on the Dynatrac ProRock 60 axles for decades – making this the strongest 44-class axle available for the Wrangler JL. It also gives these Jeeps the largest steering joint available in a 44-class axle. \u003c\/p\u003e\u003ch2\u003eWhat You Get:\u003c\/h2\u003e\u003ch2\u003e\u003cspan style=\"color: #333333;\"\u003eProRock 44™ Unlimited Front Axle\u003c\/span\u003e\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDynatrac-exclusive patented ProRock® nodular-iron, high-pinion ProRock 44™ centersection with control arm bushings installed.\u003c\/li\u003e\n\u003cli\u003eBest-in-class ground clearance and more ground clearance than a factory Dana 30.\u003c\/li\u003e\n\u003cli\u003e3.125-inch-diameter x ½-inch-thick wall tubing that is 3 times stronger than any stock JL Dana 44 housing.\u003c\/li\u003e\n\u003cli\u003eDynatrac’s forged, double-heat-treated axleshaft assemblies are included.
