JE piston kit designed for high-performance V-Twin engines. This kit from the JE PISTONS range consists of forged components and assembly accessories to replace the piston and its rings on compatible engines, while maintaining the spirit of Vintage/Classic and Touring machines.
The forged piston offers a robust structure against the thermal and mechanical stresses encountered on large twins. The kit includes all necessary assembly components for work on the top end (pins and locks), while the JE Pro Seal rings complete the package for sealing and combustion gas control. A true maintenance and restoration part, this kit is particularly aimed at owners of Harley-Davidson Softail 1340 (FXST, FXSTB, FXSTS) from 1999 and enthusiasts of classics and touring who wish to preserve the reliability and mechanical coherence of their machine.
