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 the perfect piston installation is critical for engine longevity and performance. The Auto Racing Products (ARP) 4.440-inch bore tapered ring compressor is engineered to make this task seamless. Unlike traditional adjustable bands, this CNC-machined aluminum tool features a precision-tapered entry that gently compresses rings as the piston is pushed into the cylinder bore.
By using a dedicated tapered compressor, you eliminate the guesswork associated with manually adjusted tools. This ensures that every ring is seated perfectly, promoting optimal compression and oil control from the first start-up. Whether you are performing a high-performance rebuild or a standard engine service, this tool provides the accuracy required for professional results. Trust your engine build to the best tools available at GGCRACING.
