Construction & Design
The ARP Ring Compressor (900-6250) features a meticulously CNC-machined billet aluminum tube, ensuring a perfect balance of strength and weight. Its true-radius design is engineered for each specific bore size, providing a superior fit compared to traditional tapered compressors. This design reduces the risk of ring deformation or damage during installation, which can compromise engine sealing and performance.
The reliefs incorporated into the design accommodate wire O-rings, making it compatible with various piston configurations and sealing requirements. The Type 3 anodizing process not only provides an attractive finish but also offers excellent corrosion resistance, ensuring the tool maintains its integrity over many uses. The engraved bore size markings are highly visible, allowing for quick and accurate selection during assembly.
Installation & Fitment
The ARP Ring Compressor (900-6250) is designed for easy, bolt-on installation.
