Carbon Fiber Driveshafts
BAC's patent-pending design is a mechanically integrated one-piece design where as the aluminum yokes are filament wound into the shaft. Wet composite material sinks into knurling on each yoke and encapsulates it during the manufacturing process. Therefore, each yoke is permanently locked into the shaft when the epoxy composite is cured. This revolutionary design does not rely on adhesives to transfer the torsional load from the aluminum yoke to the carbon fiber composite. Independent laboratory tests have revealed BAC's Carbon Fiber Driveshaft has significantly higher torsional strength and less weight over popular aluminum shafts and all other carbon composite driveshafts. BAC's Carbon Fiber Driveshaft is one-of-a-kind... don't settle for anything less.

Ultimate Torsion Tests for Pro-Modified Shafts

Torsion Test Results

For a typical IHRA Pro-Modified Drag Car application with a driveshaft length of 36 3/8”, BAC’s carbon driveshaft removed 6.6 pounds of rotating weight over a standard 3.0” OD chrome-moly shaft. This is a 53% weight reduction without sacrificing any strength.
Both shafts have approximately the same ultimate torsional strength. The chromemoly shaft failed at 5,667 ft•lbs and BAC’s carbon shaft failed at 5,417 ft•lbs. Also note that the BAC shaft has greater torsional flexibility (higher angle of rotation per torque load) than the steel shaft. This increased torsional flexibility absorbs impact loading (torque spikes) due to “clutch pop”. It also increases the cycle life of all other drivetrain components connected to the shaft.
