Cycle X 2nd (0.50) Over Piston Kits
Introducing our Cycle X  61.50 Piston Sets

Super high quality (exact OEM specs)
Our pistons are better. Why?
3 Piece Oil Rings - Chrome Top Ring (a must for today's fuels) 
All Cycle X pistons are now manufactured with a anti-friction  "Tin coating."
This coating has been used for 30+ years on pistons with great success.

77-78 K models had slightly smoother combustion chamber so 77-78 K model pistons had a slight dome on the piston. Because the dome height on 77-78 K pistons is very small, our pistons can be used without power loss issues.
