Water pump Gen 2 assembly for Stark VARG cooling system. Second-generation pump with improved flow and reliability over the Gen 1 unit. Includes the upgraded cover with the return pipe outlet. Direct-fit replacement for the VARG MX 1.2, EX and SM. May require a radiator upgrade for the VARG MX 1.0 if not equipped with a radiator bleeding nozzle to plug the return pipe between the water pump and the top of the radiator.
