ProRock XD60™

ProRock XD60™

Dynatrac™ introduces the next step in its revolutionary, patented ProRock® series of off-road axles with the all-new ProRock XD60®.

The Dynatrac engineering team went back to the drawing board to find ways to increase the strength and durability beyond the patented ProRock 60® which is already the industry standard for upgrades beyond the Dana 60.

Advantages of the all-new Dynatrac ProRock XD60® axle housing include:

  • The axle was designed to hold a larger differential and 10.1-inch ring gear, providing a 16 percent strength increase over 9.75-inch Dana 60 gears.
  • The patented design provides the best ground clearance in the industry.
  • The new Dynatrac ProRock XD60® starts with a center section cast from high-strength nodular iron.
  • Using CAD/FEA and advanced engineering tools, Dynatrac designed the new center section for increased rigidity, increasing the stability of critical tolerances during high stress for better durability.
  • It is also available with larger carrier and pinion bearings for even more strength.
  • The internal Dynatrac Dual Sump High Volume (DSHV) lubrication system provides optimal oiling.
  • All of these improvements were achieved while also making the center section 15 percent lighter.
  • The ProRock XD60® also has optimal cast-in features for air locker and electric locker connections.
  • In addition to these engineering advancements in the center section and wheel ends, the Dynatrac XD60® also features an all-new differential cover designed to withstand brutal beatings in demanding off-road and racing conditions. The lower bolt heads are deeply embedded in the cover for skid protection, and the fasteners are the largest in the industry: 7/16 inch compared to conventional 3/8 inch. The rock ribs have been placed for optimal protection.

The Dynatrac ProRock XD60® is designed for 3 3/4-inch outside-diameter axle tubes with either 1/4-inch or 5/16-inch wall thickness. The 1/4-inch-thick axle tubes are 22 percent stronger than a 3 1/8-inch-diameter tube with 5/16-inch wall thickness, and they weigh the same. The 5/16-inch-thick tubes are 12 percent stronger and 18 percent lighter than 3 1/8-inch-diameter tubes with 1/2-inch wall thickness.

Featuring the Dynatrac-exclusive 1550LT® Wheel Ends

  • Forged 4140, heat-treated, fixed spindles and serviceable wheel bearings support tires up to 44 inches.
  • No other 4x4 front axle offers the ease of steering, low scrub radius, effective Ackermann angle and high steering linkage positioning.
  • Dynatrac-exclusive U.S.-made forged, double-heat-treated 1550 35-spline axleshaft assemblies. These are the best shafts in the industry and are capable of up to 50-degree turning angles.

This Wayalife video explains Ackerman and scrub radius, and how the Dynatrac 1550LT® wheel end minimizes scrub radius for best-in-class steering on-road and off!

The Dynatrac ProRock XD60® accepts a full range of differentials, including air lockers, electric lockers and limited slips. Gear ratios are available from 3.54:1 to 5.38:1.

The all-new ProRock XD60® axle is now available in both front and rear applications for the 2007 to current Jeep Wrangler (JK). You can get a price estimate on a Dynatrac ProRock XD60 for your Jeep JK by filling out this online form (click here) or calling us at 714-596-4461.
