Dynatrac-Tacoma-ProRock-60-Rear-Axle-1 The Dynatrac ProRock 60® for 2005-2015 Toyota Tacoma trucks offers the legendary strength of a Dynatrac axle housing and axleshafts in a Builder’s Kit. This high-pinion ProRock 60 housing features heavy-duty suspension-mount brackets jig-fitted and welded in place to bolt to factory suspension. The axles have the correct Toyota wheel bolt pattern to accept stock or common aftermarket wheels for these applications, and it is compatible with the ABS and the stability control system. The ProRock 60 Builder’s Kit for Tacomas includes a high-pinion ProRock 60 housing, high-strength 35-spline axleshafts and Pro Series™ differential cover. This new axle includes the vital components and features that have made the ProRock 60 an icon in the industry:
  • Nodular iron center section engineered, cast and machined in the U.S.
  • Patented ProRock™ design that provides best-in-class ground clearance
  • Proprietary oiling system
  • Nodular iron diff cover with strategically-located rock ribs
The ProRock 60 Builder’s Kit is a significant improvement in rear-axle strength for Tacomas. It uses a 9.75-inch ring gear, compared to the stock 8.0-inch ring gear that comes in these trucks. The Dynatrac axleshafts are 35-spline, compared to the stock 30-spline shafts, and the Dynatrac shafts feature a unique heat-treat process for additional strength. The ProRock center section has Dynatrac legendary strength engineered into it, and the axle tubes have 0.3125-inch wall thickness, compared to 0.200-inch from the factory. The customer re-uses the brakes and ABS sensors, and he can either can supply the differential and ring-and-pinion gear of his choice to complete the axle assembly or order them separately from Dynatrac.
