Wiseco RCS41350 4.135 in Piston Ring Compressor for use with 104-105/109

Wiseco RCS tapered piston ring compressor sleeves are available for many piston sizes ranging from 65.5 to 105.1 mm. Prevent damaging modern thin piston rings that can occur when using traditional band clamp style split ring compressors. This handy engine assembly tool can be used with any piston from any manufacturer to easily compress the piston rings smoothly and evenly, providing a smooth radius and taper that greatly reduces the difficulty of installing piston rings. Each sleeve machined from a forging, hard anodized for long life, and is clearly labeled with its bore size.

Be sure to select the correct tapered sleeve by verifying your bore size before ordering. Each sleeve is bore size specific, so you cannot use it with bore sizes other than the one listed for each specific part number.
