Most people tell us that they know that the Dynatrac ProRock® axles – and XD60 axles specifically – are the ultimate in strength and durability. There’s no arguing that the patented ground clearance means that our axles give you 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 our 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.
Our 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 our most advanced 60-series axles to date. Our cutting-edge technology allows us to provide superior strength, ground clearance and steering attributes unmatched by our competitors.

For example, our Hard Core Plus Axle Set comes with our competition-series upper rebuildable HD Balljoints™ with our exclusive oversize chromoly stem and stainless bearings. That’s a $795 value that no other axle manufacturer can offer. And you can’t upgrade any other axles to accept our massive, extreme-duty ball joints.
Another standout feature can be found with our exclusive Dynatrac 1550 steering knuckle and wheel end assembly. These high-steer knuckles, with full-floating spindles and hubs are engineered to decrease scrub radius, which not only drastically reduces the stress on steering components turning bigger tires, but also equates to an effortless and predictable on- and off-road driving experience. This feature is available only on Dynatrac ProRock XD60 axles.


Since we want to make sure you have everything you need with the Hard Core Plus Axle Set, we include a heavy-duty tie-rod and DHD Drag Link Sleeve™ at no extra charge. This will add $550-$650 to “the other guys” axles.
Then there are our DynaLoc™ hubs, which are three times stronger than all other hubs on the market. They have a convenient 1/8 turn to engage and disengage. That’s a $650 value.


Another consideration is brakes. Not only does our Hard Core Plus Axle Set come with some of the best brakes in the industry, but we made sure that you won’t have to change the master cylinder or booster in order to get optimum braking. That’s a savings of up to $300 for parts alone, plus $150 for installation and at least another $100 to properly bleed the brakes on all new stability control equipped Jeeps with four-channel ABS pumps.
There are engineered advantages in the ProRock XD60 that no competitor can match at any price. There’s a nodular-iron center section designed from the ground up for the rigors of off-road use and big tires 40 inches in diameter. Using CAD/FEA and advanced engineering tools, Dynatrac designed the new center section for increased rigidity, improving critical gear tooth engagement during high stress for better durability. Our nodular-iron differential cover is held in place with industry-leading aircraft 7/16-inch fasteners, all engineered to provide ultimate strength and case stiffness.

Since we’re the only axle manufacturer offering 4-inch rear and 3.75-inch front axle tubing, we’re able to deliver a stronger axle with considerably less weight.
Our 100 percent American-made axleshafts have you covered in the strength department, so the next critical area for on the trail is our U.S.-patented ground clearance. After all, why invest in an axle set that will have your differential hung up at every turn? Unlike “the other guys,” our XD60 provides more ground clearance than any Dana 60. As a matter of fact, our XD60 has more ground clearance than a Dana 44! This means not giving up the ground clearance you gained from adding big tires, just because you need a bigger axle.

Dynatrac has designed and manufactured high-performance axle assemblies for more than 30 years. Unlike other companies, our focus has been on supplying demanding off-roaders with the most durable and strongest axles possible. Our Hard Core Plus Axle Set is a direct result of three decades of experience in doing just that. From the best brakes on the market to our no-fault warranty that puts Dynatrac service above all others, we have you covered from start to finish. When you’re ready for an axle upgrade, don’t settle for repackaged stock-axle technology.
