When your 1340cc Shovelhead cylinders need a .030" bore, this Wiseco forged piston kit provides the perfect high-compression solution. Designed for 1979 to 1984 models, these pistons bump the compression ratio to 9.5:1, offering a significant performance gain over the original 8:1 factory specifications. The forged aluminum construction provides superior strength and heat dissipation compared to cast alternatives. This kit is sold as a set and includes everything required for the job: pistons, wrist pins, circlips, and Hastings rings. The rings are designed for 1.2mm top and middle ringlands with a 4.75mm oil ring, ensuring a high-quality seal and long-lasting engine life.
