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.
Achieving a perfect seal during engine assembly is critical for performance and longevity. The Auto Racing Products 88.50mm Piston Ring Compressor is engineered to simplify the installation process, ensuring your rings slide into the cylinder bore without damage. Designed specifically for 88.50mm bore applications, this tool features a precision-tapered lead-in that compresses rings smoothly and evenly.
Whether you are a professional engine builder or a dedicated DIY enthusiast, using the right equipment is the difference between a reliable engine and a catastrophic failure. This compressor ensures that every ring is seated correctly, maintaining optimal compression ratios and preventing blow-by. Its tapered geometry is superior to traditional adjustable compressors, offering consistent pressure around the entire circumference of the piston. Trust your engine build to the industry-leading quality of ARP components. Discover more high-performance engine assembly tools available at GGCRACING.
