Regina Chain 530 DR Extra Series Chain

Regina Chain 530 DR Extra Series Chain

At the tree, a standard street chain is out of its depth on a high horsepower drag bike. The Regina 530 DR Extra Series Chain is built for violent launches, severe shock loads and hard torque spikes in competitive drag racing. Designed for strip use up to Pro Stock level, this non-sealed heavy-duty chain delivers the direct power transfer needed to cut precious time from each pass. To reduce drivetrain drag, the 530 DR Extra omits internal sealing rings entirely. Regina builds it with high-alloy steel plates, oversized pins, solid bushings and shot-peened rollers for strong fatigue resistance under sudden acceleration. With tensile strength exceeding 10,500 pounds and an impressive fatigue endurance limit, the 530 DR Extra provides the strength drag racers and high torque builders need for consistent full-power runs.
