ARP Ring Compressor

2010–2025 Universal Application for Engine Rebuilds and Performance Builds

Part #: 900-5600

Overview

The ARP Ring Compressor (900-5600) is a specialized tool designed to simplify the process of installing piston rings during engine assembly or rebuilds. Crafted with precision and durability in mind, this kit is ideal for automotive enthusiasts, professional engine builders, and performance tuners who demand accuracy and reliability. Whether you're working on a high-performance street engine or a race-ready powerplant, this ring compressor ensures a smooth, hassle-free installation, helping you achieve optimal sealing and engine performance.

Constructed from high-quality materials, the ARP tapered piston ring compressors are CNC-machined from 6061-T6 billet aluminum, offering exceptional strength and lightweight handling. The true-radius design of each compressor provides a superior fit compared to conventional tapered devices, reducing the risk of ring damage or installation errors. The relieved design accommodates wire O-rings on the bottom, making it versatile for various piston configurations. With prominent engraving of each bore size in 3/4 inch high numbers, identification and selection are quick and straightforward, saving valuable time during assembly.

Key Features

The ARP Ring Compressor kit boasts several advanced features that set it apart from standard tools:

• Manufactured from CNC-machined 6061-T6 billet aluminum for maximum strength and durability.
• True-radius design for each bore diameter ensures a perfect fit, reducing installation stress on piston rings.
• Relieved to accommodate wire O-rings, providing compatibility with a wide range of piston types.
• Type 3 anodizing finish enhances corrosion resistance and longevity, even in demanding engine environments.
• Clear, high-visibility engraving of bore sizes allows for quick identification and selection.
• Lightweight construction facilitates ease of handling during assembly.
• Designed for use with a variety of engine sizes and configurations, from small displacement engines to large V8s.

Construction & Design

The ARP Ring Compressor is meticulously CNC-machined from premium 6061-T6 billet aluminum, a material renowned for its strength-to-weight ratio and corrosion resistance. The true-radius design ensures each compressor conforms precisely to the piston bore, providing an even, secure fit that minimizes the risk of ring damage during installation. The relieved sections are carefully engineered to accommodate wire O-rings, making this tool versatile for different piston designs. The anodized finish not only adds a sleek appearance but also protects against oxidation, ensuring long-lasting performance in engine bays exposed to heat and moisture.

Installation & Fitment

The ARP Ring Compressor kit is designed for straightforward, bolt-on use. Its CNC-machined construction guarantees a precise fit for bore sizes marked on each compressor. To install, simply select the appropriate bore size, slide the compressor onto the piston, and carefully compress the ring as you insert the piston into the cylinder bore. No additional tools, cutting, or modifications are required. This tool is suitable for use with standard piston rings and is compatible with most engine rebuild setups, making it an essential addition to your engine assembly toolkit.
