Description: Ships same/next business day hassle-free returns 100% satisfaction guaranteed combined shipping available KB Pistons Cast Pistons EVO 80CI 8.6:1 Standard KB258.STD Description KB Hypereutectic alloy pistons are cast with a 16% high silicon content that has very high thermal barrier properties along with a low thermal expansion rate, allowing tight piston to cylinder wall clearances. This makes them ideal for air-cooled engines, offering optimal ring seal, quieter engine running and reduced wear. Hypereutectics are best suited for stock or mild compression ratios up to 10.5:1 running on pump fuel.Manufactured from high-strength, T-5, heat-treated, 390 hypereutectic aluminum alloy Allow a tighter fit and longer piston and ring life Diamond-machined pistons are held to plus or minus one gram weight and less than one-half-thousandth-inch (.0005") tolerances from piston to piston Each kit contains two pistons, pins, spiral-lock pin clips and Hastings moly rings Replacement piston rings and pin lock rings available separately KB pistons can be installed tighter than other pistons. This results in less piston rock and better ring seal. Please read instructions included with piston for correct piston clearance. Due to the thermal conductivity and design of KB pistons, special attention is required to the top ring end gap. Please read instructions furnished with piston for correct ring installation.
