- help control the oil film on the cylinder walls
- reduce power loss and smoke
Construction
- 2T piston ring set (usually 2 rings)
- Made from cast iron / alloy steel, matched to the Streetrace cylinder
- The top ring provides the seal during combustion
- The lower ring provides stable sliding and lubrication control
Compatibility

- after extended use (especially in a performance set-up)
What new rings give you
- restored compression
- easier starting
- pulling power restored
- more stable engine running
