To fit original aluminum Norton rods
Replace the original Hepolite or JCC pistons with high quality American made forged pistons. Stronger and lighter than stock pistons but not as ideal as our lightweight piston/long rod combo. (BALANCE INFO).
Medium or High Compression 750 to 1007cc
If you want a tight installation clearance then you must have us coat your pistons to avoid scuffing.
Uncoated
