• Premium Material Construction: CNC-machined from 6061-T6 billet aluminum, the compressor provides exceptional strength and lightweight handling, ensuring durability over many uses.
• True Radius Design: Each bore diameter features a true radius tailored to specific piston sizes, resulting in a more precise and secure fit around the piston rings.
• Relieved for Wire O-Rings: The compressor is relieved to accommodate wire O-rings on the bottom, making it suitable for a variety of piston designs and ensuring a tight seal without damaging the rings.
• Long-lasting Finish: Type 3 anodizing enhances corrosion resistance and longevity, maintaining the tool's appearance and functionality over time.
• Easy Identification: Bore sizes are prominently engraved in 3/4 inch high numbers, allowing quick and accurate selection during assembly.
• Precision Machining: The CNC machining process ensures tight tolerances and smooth surfaces, reducing the risk of scratches or damage to piston rings.
• Versatile Compatibility: Suitable for a wide range of bore sizes, making it a versatile addition to any engine builder's toolkit.
• Enhanced Safety: The true-radius design minimizes the risk of ring deformation or breakage during installation, promoting engine reliability.

Construction & Design

The ARP Ring Compressor is meticulously engineered from high-grade 6061-T6 billet aluminum, known for its excellent strength-to-weight ratio and corrosion resistance. The CNC-machined construction guarantees precise bore diameters and smooth surfaces, which are critical for proper ring compression and installation. The true-radius design of each bore ensures that the piston rings are evenly compressed, reducing the likelihood of ring distortion or damage.

The reliefs incorporated into the design accommodate wire O-rings, expanding the tool's compatibility with various piston configurations. The Type 3 anodizing not only provides a sleek, durable finish but also protects against corrosion, ensuring the tool remains in optimal condition through numerous uses. The prominent engraving of bore sizes allows for quick identification, streamlining the assembly process and reducing potential errors.

Performance & Benefits

Using the ARP Ring Compressor (900-0700) ensures a smooth, controlled compression of piston rings, which is essential for proper seating and sealing within the cylinder bore. Its precise machining and thoughtful design help prevent ring damage, ensuring a tight seal that supports optimal compression ratios and engine efficiency. The lightweight yet robust construction makes handling easier, especially in tight engine bays or when working on high-performance builds.

While this tool does not directly increase horsepower, it plays a crucial role in achieving a reliable and properly assembled engine, which is fundamental for optimal performance. Its durable construction and ease of use make it a valuable addition to any engine builder's arsenal, whether for professional shops or dedicated enthusiasts.

Installation & Fitment

The ARP Ring Compressor is a straightforward, bolt-on tool that requires no special modifications or adjustments. Simply select the appropriate bore size, position the compressor around the piston rings, and compress the rings evenly as you insert the piston into the cylinder. The true-radius design ensures a snug fit, reducing the effort needed and minimizing the risk of ring damage. No cutting, drilling, or tuning is required, making it an efficient and user-friendly tool for engine assembly.
