Regina Chain 530 DR Extra Series Chain

Regina Chain 530 DR Extra Series Chain

When you are staging at the tree and preparing to dump the clutch on a high-horsepower drag bike, a standard street chain simply will not cut it. The Regina 530 DR Extra Series Chain is purpose-built to survive the violent launches, brutal shock loads and intense torque spikes of competitive drag racing. Engineered to meet the punishing demands of strip duty all the way up to Pro Stock level, this non-sealed heavy-duty chain delivers the maximum power transfer required to shave critical fractions off your elapsed time.

Because every ounce of friction counts when you are chasing the timing lights, the 530 DR Extra skips internal sealing rings to eliminate parasitic drivetrain drag entirely. Regina constructed this drag strip beast using high-alloy steel plates, oversized pins, solid bushings and shot-peened rollers that deliver massive fatigue resistance against sudden snap acceleration. With an astounding tensile strength over 10,500 lbs and an exceptional fatigue endurance limit, the 530 DR Extra gives drag racers and high-torque builders the unyielding strength needed to lay down full power run after run.
