Driveshaft Carbon 37.5in Crate LM w/o Yoke

The QA1 Driveshaft Carbon 37.5in Crate LM without Yoke is a high-performance driveshaft purpose-built for dirt late model racing applications. This carbon fiber driveshaft delivers the lightweight construction and durability required for competitive dirt oval racing, where reducing rotational mass directly translates to better acceleration and lower lap times. At 37.5 inches in length with a 2.25-inch outer diameter and 1310 U-joint configuration, this universal shaft is engineered to handle the unique torque demands and vibration profiles of late model racing powerplants.

Carbon fiber construction significantly reduces weight compared to steel alternatives while maintaining structural integrity under racing conditions. The 1310 U-joint specification is the industry standard for this class of vehicle, providing proven reliability in high-RPM, high-torque environments. The 2.25-inch diameter balances strength with minimal weight penalty—critical in a racing application where every pound of unsprung mass affects chassis dynamics and tire contact. This crate configuration ships without the yoke, allowing you to specify or retain existing yoke hardware matched to your transmission and rear differential setup.

This driveshaft is ideal for dirt late model competitors rebuilding or upgrading their drivetrain, whether for track preparation, seasonal overhaul, or performance optimization. QA1's established reputation in the racing suspension and drivetrain market reflects their commitment to precision engineering. The universal design accommodates various transmission and differential combinations, making it a practical choice for teams running different configurations across a fleet or planning future drivetrain changes. Proper installation and U-joint maintenance are essential for driveshaft longevity in racing service.
