JE Pistons’ forged 8-cylinder nitrous-dome piston kit is crafted for BBC nitrous and high-output builds, forged and machined in the USA. The FSR forging reduces skirt width and friction, while accumulator grooves and skirt coatings (when applicable) improve ring control and cut wear and noise. This kit is specified for a 4.600 in bore with a 1.270 in compression dish (44.0 cc).
