The Dynatrac ProRock® axles – and XD60 axles specifically – are often regarded the ultimate in strength and durability. There’s no arguing that the patented axles give you some of the best ground clearance. Period. But most people believe that a Dynatrac Hard Core Plus Axle Set™ for the Jeep Wrangler JK, Jeep Wrangler JL and Jeep Gladiator JT is much more expensive than other 60-class crate axle offerings. The reality is that their Hard Core Plus Axle Set may actually save you $2,500 compared to the competitors’. In fact, even if you pay more to upgrade to “the other guys” axles, you still won’t get many of the exclusive features and benefits you’ll find in Dynatrac ProRock XD60® axles.
The Hard Core Plus Axle Set is a prime example of modern technology and American innovation combined for the greater good. Designed for up to a 40-inch-tall tire, the Hard Core Plus Axle Set uses Dynatrac’s most advanced 60-series axles to date. Dynatrac’s cutting-edge technology provides superior strength, ground clearance and steering attributes.
The 1550LT® steering knuckle is engineered to decrease stress on your steering with the best scrub radius of any front axle for the Jeep Wrangler JK and JL and the new Jeep Gladiator JT. This not only reduces the likelihood of a steering component failure, but also makes for an easier driving experience on-road and off.
Another advantage of the ProRock XD60 that comes in the Hard Core Plus Axle Set is the high position of the tie rod; there’s no need for a flip kit or high-steer kit, which can create problems with the factory Jeep JK, JL and JT steering system and many aftermarket suspension systems. The position of the tie rod for most Dana 60s, including our original ProRock 60. Below shows how the XD60 tie rod position is much less prone to rock damage, being 2.4 inches above the axle centerline.
