The JE Pistons Ultra Series forged piston set for Ford 5.0L Coyote Gen 3 gives your performance engine build a durable foundation for demanding use. Forged from 2618 aluminum, these Ultra Series pistons combine JE's application-specific engineering with features developed for demanding performance builds. This kit pairs an FSR forging with lateral gas ports, an accumulator groove, skirt coating, and Thermal Crown treatment. Carefully machined crown geometry, ring grooves, and pin bores bring those features together in a piston designed around its engine application. This 3.661 in bore kit uses a 1.168 in compression height and is supplied as a matched set of eight pistons for your next V8 build.
