Moly Driveshaft 29in Long- 2in Dia.

The Moly Driveshaft 29in Long- 2in Dia. from FAST SHAFTS is engineered for street machines, circle track competitors, and hot rod builders who demand lightweight driveline components with real-world durability. This 29-inch molybdenum driveshaft replaces heavy steel units while maintaining structural integrity under aggressive acceleration, high-RPM launches, and sustained power delivery. Whether you're upgrading a classic muscle car, custom street rod, or performance daily driver, a quality driveshaft is foundational to translating engine power to the wheels without vibration, noise, or catastrophic failure.

Molybdenum construction delivers a 40–50% weight reduction compared to traditional steel shafts, lowering rotational mass and improving acceleration response without sacrificing strength or torsional stiffness. The 2-inch diameter tube profile is balanced and dynamically tested to eliminate vibration across the entire RPM band, a critical factor when running larger engines or high-horsepower applications. FAST SHAFTS' precision 1350-series or 1410-series U-joint compatibility ensures secure connection to your transmission and axle housing while accommodating the exact 29-inch length specification required for mid-sized chassis and custom mounting scenarios.

This driveshaft is ideal for builders transitioning from stock or sleeved steel units to lightweight performance setups, particularly those targeting 0–60 mph acceleration improvement and sustained track use. Installation requires standard U-joint coupling at both transmission and rear-axle flanges; measure center-to-center distance and verify yoke compatibility before ordering. At 8.8 lbs, the weight savings compounds with other chassis upgrades to improve handling balance, braking feel, and overall vehicle responsiveness—benefits most noticeable on dedicated performance machines or vehicles with manual transmissions where driver feedback is paramount.
