ARP 900-1450 Billet Aluminum Piston Ring Compressor

The ARP 900-1450 is a precision-engineered piston ring compressor designed for professional engine builders and serious enthusiasts. CNC-machined from 6061-T6 billet aluminum tube material, this compressor features a true radius design specifically tailored to match the bore diameter, providing superior performance compared to conventional tapered compressors.

Key Features:

• CNC-machined from 6061-T6 billet aluminum for exceptional strength and durability
• True radius design matches bore diameter precisely for optimal piston installation
• Bottom relief designed to accommodate wire O-rings
• Type 3 hard anodized finish for long-lasting wear resistance
• Bore size prominently engraved in 3/4-inch high numbers for quick identification
• Professional-grade tool widely acclaimed by engine builders

The true radius design ensures even compression around the entire piston ring pack, preventing ring damage during installation and making piston insertion smoother and more controlled. The hard anodized finish provides a durable, low-friction surface that resists galling and wear even after repeated use. This is an essential tool for anyone performing quality engine assembly work.
