ARP Stainless Water Pump & Thermostat Housing Bolt Kit (LS1 & LS2 Engines) – 434-3201

Water leaks are never a good thing but fortunately ARP has a solution. Their premium grade water pump bolts are designed and engineered to engage the threads in the engine block and resist loosening due to heat cycles and vibration. They are application specific and come in your choice of chrome-moly with a black oxide finish or rust resistant stainless steel. You can also order them with 12-point or hex heads. Washers are included.
