JE Pistons forged eight-piece piston set for 5.4L 3‑valve modular engines at 8.5:1 compression. These pistons use a 3.572 in. bore, 1.320 CD and -31.2 cc specification and reflect JE’s competition-proven design. The Forged Side Relief forging reduces skirt width and friction; pistons may include an accumulator groove and skirt coating depending on application. Forged from 2618 aluminum and machined in the USA, they’re built for the intended engine use.
