ProRock 60 Builder’s Kit for Tacoma
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.
