The components in this assembly are well-built for performance. The forged 4140 crankshaft and 4340 I-beam connecting rods are strong choices for handling the stresses of racing. The Mahle pistons are forged from 4032 aluminum, known for its good thermal expansion properties, and feature an 18cc dome to achieve a specific compression ratio when paired with your cylinder heads. The inclusion of ARP rod bolts means you have reliable fasteners for the connecting rods. The plasma-moly file-fit rings allow for precise gapping to match your engine's bore and desired performance characteristics, and the King XP bearings are designed for demanding use.

This assembly is balanced from the factory, saving you a significant step in the engine building process. Please note that this assembly is not CARB approved and cannot be shipped to California.
