JE Pistons forged eight‑cylinder piston set for 5.4L Ford engines at 8.5:1 compression, made and machined in the USA. JE's process tailors pistons to the engine application, employing FSR forging to reduce skirt width and friction and optional accumulator grooves and skirt coatings to improve ring seal and reduce wear—attributes aimed at demanding street and track V8 builds.
