Drive Shaft Carbon Fiber 2.25in Dia 37.5in Long

The Drive Shaft Carbon Fiber 2.25in Dia 37.5in Long is engineered for builders and mechanics who demand lighter rotating mass and superior performance in high-horsepower applications. This universal driveshaft replaces stock units in street rods, drag cars, and modified trucks where weight reduction and vibration control are critical. Whether you're building a custom hot rod or upgrading a performance vehicle, carbon fiber construction delivers the rigidity of traditional steel at nearly half the weight—directly translating to faster acceleration, reduced parasitic losses, and improved handling dynamics.

Manufactured by FAST SHAFTS, this 37.5-inch driveshaft features a 2.25-inch outside diameter and dual 1310 U-joints—a proven configuration for street and strip use. The carbon fiber composite construction maintains structural integrity while shedding approximately 60% of the weight compared to equivalent steel shafts, reducing unsprung mass and rotational inertia for measurable performance gains. The 1310 U-joint design provides excellent articulation angles and load capacity suitable for vehicles with aggressive suspension geometry, while the 37.5-inch length accommodates most rear-engine and mid-engine layouts common in custom builds and restorations.

This universal driveshaft is ideal for enthusiasts upgrading vintage muscle cars, constructing tube-frame race vehicles, or modifying independent rear suspension installations where standard shaft lengths don't fit. Proper installation requires alignment with your transmission output and differential input flanges; most builds benefit from a driveshaft shop consultation to confirm fit and balance. At 7.6 lbs, the carbon fiber construction significantly reduces drivetrain reciprocating weight, improving engine response and fuel economy in lighter vehicles while enabling higher rev limits without exceeding critical shaft speeds. Compatible with 1310 U-joint equipped transmissions and differentials, this shaft delivers measurable improvements in acceleration feel and responsiveness in any performance application.
