ARP 900-1300 Piston Ring Compressor Tool

The ARP 900-1300 piston ring compressor is a precision-engineered tool designed for professional engine assembly. CNC machined from 6061-T6 billet aluminum tube material, this compressor features a true radius design that matches the specific bore diameter for accurate, damage-free piston installation.

Key Features:

• True radius design provides superior performance compared to conventional tapered compressors
• CNC machined from 6061-T6 billet aluminum for precision and durability
• Type 3 hard anodized finish for extended service life and wear resistance
• Relieved bottom edge accommodates wire O-rings without interference
• Bore size prominently engraved in 3/4-inch high numbers for quick identification
• Professional-grade tool widely used by expert engine builders

This ring compressor ensures proper piston installation by evenly compressing rings as the piston enters the cylinder bore, preventing ring damage and reducing installation time. The true radius design eliminates the gaps and uneven compression common with tapered tools, making it an essential tool for quality engine assembly work.
