9.5:1 Compression Ratio - for Parallel Valve 5.125 Bore
For Experimental or Ground Use Only
This piston is made in the USA from a high quality forging as are all pistons manufactured by Combustion Technologies. This piston is a high compression replacement for Lycoming parallel valve engines. This piston is made from a forging - this is why anodizing in the ring groove area is not necessary.
