140010 Piston ring compressor kit

A good piston ring compressor is essential for a smooth top-end assembly, and this George’s Garage kit is as versatile as they come. It is designed to handle pistons ranging from 2 7/8 inches up to 4 3/8 inches, or roughly 73.1mm to 111mm. The kit includes six different sizes of compressor bands, making it a universal solution for almost any Harley engine build you have on the lift. Whether you are working on an Ironhead or a big-bore Milwaukee-Eight, these bands provide even pressure to safely guide the rings into the cylinder without breakage. It is a shop staple that takes the stress out of engine assembly.
