C/F Driveshaft 3-1/4in Dia 38-1/2in Long

The C/F Driveshaft 3-1/4in Dia 38-1/2in Long from WILES RACING DRIVESHAFTS is purpose-built for high-performance and custom vehicle applications where durability and precision engineering are non-negotiable. Whether you're upgrading a street rod, drag car, or custom hot rod, this carbon fiber composite driveshaft delivers the lightweight advantage that modern enthusiasts demand without sacrificing structural integrity. Engineered for vehicles requiring robust torque handling and extended length specifications, this driveshaft combines racing heritage with practical day-to-day reliability that you can trust on the dyno or the road.

At 3-1/4 inches in diameter and 38-1/2 inches long, this carbon fiber composite driveshaft weighs just 9.8 pounds—a significant reduction compared to traditional steel alternatives that would add unnecessary rotational mass to your drivetrain. The carbon fiber construction reduces vibration transmission while maintaining the torsional rigidity required for high-horsepower applications, allowing your engine's power to transfer more efficiently to the wheels. The composite material resists corrosion and fatigue better than conventional steel, ensuring consistent performance through thousands of heat cycles and demanding driving conditions.

Mechanics and fabricators favor WILES RACING DRIVESHAFTS for rebuild projects, restorations, and performance upgrades where OEM specifications fall short of modern engine output. The 38-1/2-inch length accommodates mid-length frame configurations common in custom builds and street rods, while the 3-1/4-inch diameter matches standard universal joint interfaces found in most manual and automatic transmissions. Installation requires proper driveline alignment to maximize component lifespan—ensure your transmission output and differential pinion are centered along the driveshaft's axis for optimal results.
