The ARP Chevy Oil Pump Stud Kit (Part No. 230-7004) is a chromoly fastener system designed specifically for high-volume oil pump installations on Chevy V8 engines. This kit replaces factory studs with premium-grade chromoly studs paired with 12-point nuts, engineered to handle the increased stress and thermal cycling associated with performance and high-volume pump applications. The black oxide finish provides corrosion resistance while maintaining a professional appearance under the engine bay.
Chromoly construction offers superior tensile strength compared to standard fasteners, reducing the risk of stud stretch or failure during extended operation or aggressive engine duty cycles. The 12-point design distributes clamping force more evenly than conventional 6-point fasteners, minimizing stress concentration and improving bolt preload consistency. The black oxide coating resists oxidation without the brittleness associated with some plating methods, making these studs reliable for underhood environments exposed to oil, heat, and moisture. Each stud and nut pair is precision-manufactured to ARP's documented specifications.
This kit targets engine builders, performance enthusiasts, and restoration specialists working with small-block or big-block Chevy V8s equipped with high-volume pump setups. High-volume pumps deliver greater oil flow than stock units, increasing parasitic drag on the crankshaft and placing higher loads on the pump mounting studs. Upgrading from OEM fasteners to this ARP chromoly kit reduces the risk of pump detachment or stud failure during sustained operation, making it an essential upgrade for street performance, racing, or high-mileage engine rebuilds.
ARP is recognized in the engine building and motorsports community for fastener engineering and quality control. This stud kit represents a straightforward, cost-effective insurance policy against pump mounting failure, applicable across generations of Chevy V8 platforms where aftermarket or OEM high-volume pump conversions are common.
