Drag Race Chain

EK drag racing chains can rightfully be called the fastest chains in the world. Top Fuel champion Larry “Spiderman” McBride set a world record E.T. of 5.876 seconds using the EK 630SHB chain. The EK 530DRZ has achieved a terminal velocity of 338.269 mph on Sam Wheeler’s E-Z-Hook Streamliner at the Bonneville Salt Flats. The EK 530DRZ is also the choice of more top NHRA Pro Stock motorcycle racers than any other chain.
