CHEVY LS 3.900 STROKER WITH .927 PI

These LS pistons are optimized for 3.900 stroke rod angle which provides smoother and more precise operation, reducing bore distortion, crank and rod stress, and aiding in maintaining a consistent ring seal. An increased compression height design reduces piston rock and improves stability in the cylinder, aiding in more consistent ring seal for reliable performance. These pistons are forged In-house from 2618, high tensile strength alloy and include H13 wrist pins and 1.2mm, 1.2mm, 3.0mm GFX ring pack to complement the necessary strength and durability needed in power-adder applications.
