The S/S W/P & Thermostat Hsg Bolt Kit - 6pt. LS1/LS2 is a premium fastener upgrade designed for serious LS engine builders and performance enthusiasts who demand reliability under high heat and stress. These stainless steel bolts replace the factory hardware securing the water pump and thermostat housing—critical components that experience constant thermal cycling and vibration.
ARP's 6-point stainless steel bolts offer superior strength and corrosion resistance compared to OEM zinc-plated hardware. The 6-point head design distributes load more evenly than 12-point fasteners, reducing the risk of stripping and providing superior torque holding power. Stainless construction resists rust and degradation in high-temperature coolant environments, ensuring longevity even in aggressive engine bay conditions.
This kit is engineered specifically for LS1 and LS2 platforms, making it the ideal choice for third-generation Corvette owners, Camaro SS builders, and truck enthusiasts upgrading their small-block or big-block LS mills. Installation is straightforward, allowing for quick upgrades to enhance engine performance and reliability.
