Product Details

Forged from 2618-T61 aluminum alloy, these JE Pistons are built for serious performance in your LS1 engine. The 15-degree valve angle design is specifically chosen to work with cylinder heads that have a matching 15-degree intake valve angle, ensuring proper valve-to-piston clearance and optimal combustion chamber sealing. This set includes eight pistons, enough to rebuild your entire V8 engine, and they are designed to fit a variety of popular GM vehicles from the late 90s and early 2000s.

JE Pistons is well-known for their robust construction, and these pistons are no exception. The 2618-T61 aluminum offers a good balance of strength and thermal expansion properties, making it suitable for boosted or high-compression applications where durability is key. The 'FT' designation in the part number typically refers to a flat-top piston design, which is versatile for many build types, allowing you to achieve your desired compression ratio with the right head gasket and cylinder head combination. These pistons are designed to be a direct replacement for the factory pistons in your LS1 engine, simplifying the installation process for a rebuild.

When undertaking an engine rebuild with these pistons, it's important to ensure all related components are up to spec. This includes checking your cylinder walls for straightness and finish, ensuring your connecting rods are balanced and straight, and using the correct ring set and wrist pins, which are often included with JE piston sets. Always refer to the manufacturer's detailed installation instructions for precise ring gap, bearing clearance, and piston-to-wall clearance recommendations to get the most out of this well-built set.
