It's put together with components designed to handle the demands of competition, whether you're running exotic fuels, heavy nitrous, or high boost applications. This assembly includes everything you need to get your short block started right.

At the heart of this assembly is a 3.750-inch forged 4340 crankshaft, known for its strength and durability under stress.

The pistons are forged 2618 JE units, featuring a -5.6cc dome to help achieve your desired compression ratio with a 4.125-inch bore. They come with plasma-moly file-fit rings, allowing for precise ring gap setting tailored to your build. Finally, the assembly is completed with King XP rod and main bearings, recognized for their advanced materials and construction that help manage load and reduce friction.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. Please ensure you consult with your engine builder or refer to manufacturer specifications for proper installation and tuning to match your specific engine build and intended use.
