Cast Piston Kit TC96 to 103CI 10.0:1 STD

• Bore Size: 3.875"
• Compression Ratio: 10.0:1
• Piston Material: Hypereutectic Alloy
• Type: Piston
• UPC: 800745151445

• Manufactured from high-strength, T-5 heat-treated, 390 hypereutectic aluminum alloy
• Allows 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 sold 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
• Use lock rings Part #0913-0001 (4-pk)

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.
