Viper ZB V10 ALL YEARS CORE EXCHANGE High Flow Pump Assembly


SKU: VIPER-S1 Categories: , Tag:

The Dodge Viper and its 8.3L V10 is one of the purest examples of domestic sports cars. These engines can produce massive horsepower under naturally aspirated and boosted conditions. That horsepower places heavy loads on the entire line of main and rod bearings along with the oil pump itself. Boundary’s introduction into the ZB series Viper is a core exchange program. It takes an existing viper core and completely refurbishes and repairs existing viper covers while increasing the pressure and flow performance of the oil pump assembly.
