- Big Bore kit yields excellent results with stock cylinder heads
- Stock engine height is maintained so there are no manifold or frame fitment issues
- Cylinders feature increased fin area for better heat dissipation, and the centrifugal cast gray iron liner features 40,000 psi tensile strength for superior wear and performance
- Easy installation no need to bore or split existing cases, just swap the cylinders (unless otherwise noted)
- The pistons in this kit have a 10cc pop-up dome for slightly higher compressoin ratio
- For 98" twin cam motors
- Kit includes cylinders, pistons, rings and gaskets (head, base and exhaust)
- For 1999-'06 Big Twins
- Made in the U.S.A
- Project requires a skilled technician. It is the responsibility of the person assembling the parts to check all clearances and assembly specifications
