Wiseco Pistons Ring Compressor Sleeve

The Wiseco Piston Ring Compressor Sleeve (also called a tapered ring compressor or piston installation sleeve) is a precision tool for installing pistons during a high-performance engine build. Each sleeve is made for a specific bore size. It compresses the piston rings smoothly and evenly as the piston is pushed into the cylinder.

Key Features:

• Machined from Wiseco sleeve forgings, for the same toughness as Wiseco forged pistons
• Hard anodized and Teflon coated for low friction and long wear life
• Smooth radius that tapers down to the specific bore size, which makes piston installation easier
• Compresses the rings evenly, which helps prevent bent or broken rings
• Makes it much easier to install thin, high-performance oil rings
• Fixed-size, non-adjustable design with a tight, consistent fit
• Marked with its bore size for easy identification

These sleeves can be used with pistons from any manufacturer, not only Wiseco pistons. They suit engine builders and racers who want accurate, repeatable ring compression and lower risk of ring damage during assembly.
