Engine Application & Fitment

This tool is specifically sized for the most common air-cooled Volkswagen engine configurations:

Tech Tip: Before installing your cylinders, verify that the ring gaps are staggered according to your assembly manual (typically 120 degrees apart). Liberally coat the rings, piston skirts, and the inside of the compressor tool with clean engine oil. This reduces friction and allows the cylinder to seat over the rings with minimal force.
