These rods come equipped with 7/16-inch ARP 8740 bolts, known for their reliability in high-stress applications. The pistons are forged 4032 aluminum flat-tops from Mahle, featuring a -8cc dish to help achieve your desired compression ratio, and they come with plasma-moly file-fit rings for a good seal. To ensure proper bearing performance and longevity, the assembly includes King XP rod and main bearings.

This assembly comes balanced from the factory, saving you a significant step and ensuring your engine runs smoothly and reliably.
