Driveshaft Carbon 29.5in Modified w/Yoke

The QA1 Driveshaft Carbon 29.5in Modified w/Yoke is a high-performance carbon fiber driveshaft engineered for dirt-modified racing and high-horsepower applications. Measuring 29.5 inches long with a 2.25-inch outer diameter, this universal driveshaft combines lightweight construction with the durability required for competitive motorsport environments where power delivery consistency and minimal drivetrain vibration are critical to lap times and vehicle control.

Carbon fiber construction significantly reduces rotating mass compared to steel equivalents, which translates to faster acceleration and reduced strain on transmission components during aggressive power application. The driveshaft features 1310 U-joints rated for the torque demands of modified engine packages and an 8-inch slip yoke that accommodates suspension travel and engine movement without binding. The 1310 joint size handles the power output typical of dirt-modified racing platforms while the slip yoke design allows suspension geometry changes without requiring driveshaft modifications. This combination ensures smooth power transfer across a range of operating conditions common in short-track racing.

Builders and drivers of dirt-modified race cars, street rods, and performance builds rely on QA1 driveshafts when factory equipment cannot handle modified power levels or when weight reduction improves chassis performance. The universal fit design allows installation across multiple vehicle platforms and custom builds where standard driveshaft options are unavailable or inadequate. Proper installation and balancing are essential to achieve the smoothness and longevity this component offers in high-demand applications.

QA1 is recognized in the racing community for manufacturing driveshafts that meet the demanding specifications of short-track racing, modified drag racing, and custom automotive builds where reliability and performance cannot be compromised.
