C/F Driveshaft 2-1/4in Dia 34.5in Long

The C/F Driveshaft 2-1/4in Dia 34.5in Long by Wiles Racing Driveshafts is purpose-built for serious street and strip applications where lightweight construction and durability are non-negotiable. Carbon fiber driveshafts have become the standard in performance automotive builds—from drag racing and road course competition to high-horsepower street machines—because they eliminate the rotational mass that steel alternatives carry. This 34.5-inch shaft with a 2-1/4-inch diameter is engineered to handle aggressive power delivery while maintaining the critical balance and safety margins required in modern performance vehicles.

Carbon fiber construction delivers superior strength-to-weight ratio compared to traditional steel or aluminum driveshafts, translating directly into reduced parasitic loss and quicker acceleration. The 2-1/4-inch diameter provides adequate wall thickness for high-torque applications while the 34.5-inch length accommodates mid-sized builds with moderate wheelbase. At just 8 pounds, this shaft significantly cuts rotational inertia—particularly important in the driveline where energy losses compound through the transmission and rear differential. Wiles Racing's engineering ensures proper concentricity and dynamic balancing, minimizing vibration and extending component life under sustained high-RPM operation.

This driveshaft suits turbocharged, supercharged, and naturally aspirated builds running in the 500–1200+ horsepower range, making it ideal for bracket racers, drag competitors, and road-course enthusiasts. Installation requires proper yoke sizing to match your transmission output and differential pinion—verify your vehicle's specific flange configuration before purchase. The compact 47.5-inch shipping length accommodates standard carriers, and the four-quarter-inch grid dimensions ensure clearance in most modern and classic platforms. Complementary components like slip yokes, safety loops, and flex couplers should be selected to match this shaft's specifications for optimal safety and performance.
