Swivel Driveshaft - WP Style w/Ball 29in.

The Swivel Driveshaft - WP Style w/Ball 29in. is a precision-engineered component purpose-built for sprint car racing and high-performance motorsports applications. This hollow steel shaft delivers the articulation and reliability demanded by competitive drivers who need responsive power transfer without excessive weight. The 29-inch length and WP-style swivel design accommodate the tight packaging and dynamic suspension movements inherent in sprint car setups, where driveshaft angles shift continuously during acceleration, cornering, and braking.

Manufactured by Diversified Machine from high-strength steel in natural finish, this swivel driveshaft features a ball-end connection with 32 x 20 spline configuration, ensuring secure engagement with compatible transmission and differential housings. The hollow construction reduces rotational inertia and unsprung weight—critical factors in sprint car performance where every pound matters. The swivel ball design allows controlled angular deflection, protecting drivetrain components from the shock loads and misalignment that occur during aggressive shifting and tight-radius cornering. Measuring 2.5 x 2.5 x 29.5 inches and weighing just 5.85 lbs, this shaft strikes the balance between structural integrity and weight optimization that competitive teams demand.

Sprint car builders and mechanics standardly specify this configuration for fuel-burning and non-wing sprint classes where chassis geometry and suspension travel require articulated driveshaft solutions. The 32 x 20 spline ball end ensures compatibility with common sprint car transmissions and rearend housings built to sprint racing standards. Installation requires proper alignment and support—the swivel joint eliminates the need for expensive U-joint rebuilds while maintaining the precise depth and centerline geometry that modern sprint chassis demand. Each shaft ships individually and is ready to bolt into your existing drivetrain upon receipt.
