ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
For demanding engine builds that require extra support, the ARP M12 ID 1.55 OD .250 Thick Chamfer Black Washer is the ideal solution. This heavy-duty washer is engineered to withstand massive clamping forces, making it perfect for high-boost turbo applications or high-compression naturally aspirated engines. Its increased thickness and chamfered design ensure it sits perfectly against the fastener head and the engine block or component surface.
When you are tightening critical fasteners to high torque specs, a standard washer may not suffice. This ARP washer provides the structural integrity needed to prevent fastener pull-through and ensures that the clamping load is distributed over a wider area. The chamfered edge also helps in clearing tight spots around the fastener seat, preventing interference with surrounding engine components.
GGCRACING understands the needs of professional engine builders and enthusiasts alike. We provide individual, high-quality components like this ARP M12 washer so you can get exactly what you need for your project without buying excess parts. Trust our expertise and shop our full catalog of performance hardware for your next engine build.
