The RCV Big Bell Axle Set is the ultimate front axle solution for 2005+ Ford F-450 and F-550 Super Duty trucks running the factory Dana 60 Super-60 unit bearings. This system uses RCVs proven 2.5-ton Rockwell Big Bell CV design, adapted with a custom outer stub that fits directly into the large 32-spline Super-60 unit bearing.
By eliminating traditional lockouts or drive flanges, the Big Bell setup removes multiple failure points while significantly increasing strength, reliability, and smooth power delivery under extreme load.
This kit is designed for custom inner axle configurations and supports 40-spline or 47-spline inner shafts, making it ideal for ultra-heavy builds, high-horsepower applications, and extreme off-road or work-truck abuse.

Tech Insight
RCV Big Bell CVs were originally developed for 2.5-ton Rockwell military axles, making them one of the strongest CV systems available. By adapting this architecture to the Ford Super-60 platform, RCV delivers smooth, bind-free torque transfer with unmatched strengthwithout the compromises of hubs or flanges.
This design is ideal for trucks that see massive tire loads, diesel torque, towing stress, and extreme off-road conditions, where traditional Dana 60 components simply arent enough.
