The 4.130-inch pistons are forged from 2618 aluminum, a material chosen for its durability under extreme temperatures and pressures, and they feature a flat-top design with a slight dish to help achieve specific compression ratios when paired with appropriate cylinder heads. The included file-fit rings allow for precise gap setting, which is crucial for optimal performance and sealing in a high-performance engine.
When putting this rotating assembly into your LS7 build, remember that it's designed for competition use. Ensure you follow proper assembly procedures and torque specifications, especially for the ARP rod bolts and main bearings. This kit is not CARB approved and cannot be shipped to California. Always consult your engine builder or manufacturer's guidelines for the best results.
