Official Release:

Engine builders now have 127 different sized Tapered Ring Compressors to choose from in ARP’s extensive collection. The expanded selection ranges from 3.552” to 4.750” and 75mm to 100mm on the Metric side. These superior quality, precision CNC machined 6061-T6 aluminum billet tube compressors have a true radius for each different bore diameter and feature a relief to accommodate block O-rings and ensure proper seating.

Designed for the professional, bore sizes are prominently engraved in large .” tall letters, and Type 3 anodizing is employed to assure long service life.

They are far more efficient than clamp-style tools and guard against damage to the piston rings during the assembly process.

Features:

• 127 different sized tapered ring compressors now available
• Ranges from 3.552-4.750 inches and 75-100 millimeters
