Wiseco GM LSJ +5cc Dome 1.224x3.3858in 10:1 CR Custom Piston - Single

Wiseco is well-known for making strong internal engine components, and this custom piston for GM LSJ engines is no exception. If you're rebuilding or modifying your LSJ engine and aiming for a 10:1 compression ratio, this piston is a solid option. It features a +5cc dome, which is a key factor in achieving that specific compression target when paired with the right cylinder head volume.

This piston is machined from durable aluminum, a common material for high-performance pistons because it's lightweight and handles heat well. The pin bore size is 1.224 inches, and the overall diameter is 3.3858 inches, ensuring it's built to precise specifications for a proper fit within the cylinder. While it's designed for custom builds, it's important to note that this piston is not CARB approved and cannot be shipped to California.
