Kit includes: High Compression Easy Start Pistons, Piston Ring Set, Liners, Connecting Rod Bolts and Bushings, and Gasket set with Crank Seals
High Compression Easy Start pistons are produced from an aluminum hypereutectic alloy. This allows the pistons to: Retain a higher percentage of strength and hardness during normal operations, Have a very low coefficient of thermal expansion, Have a higher resistance to wear, Have a higher tensile strength. The combustion bowls in these pistons are engineered to create higher compression. These pistons raise the static compression of an engine approximately 1-1.5 points. They ignite a larger ratio of fuel / air per stroke, which wastes less raw fuel. This translates into: Improved cold weather starting, Increased horsepower, Extended engine life
Kit does not include connecting rod or main bearings
